Version 1.7.5

Released Jun 25, 2026 07:03

What’s New

NEW

• Research: Freeze, Splash, Dynamites & Claymore!
• Turret limits!

UI
• ManagementUI now uses scientific notation when it becomes to big :)

BUGS
• Inbox scrolling and width fixed

OTHERS
• All balancing settings are now controlled from backend, no more releases needed to rebalance the game :)

Full Changelog

NEW MAPS!

The map rendering system received a small upgrade, allowing me to break away from the standard 9x16 grid.

The result: two brand-new maps!

  • Mini-Me! (10x10)
  • Maxi-Me! (12x20)

I also retired the three least-played maps to keep the Map Select screen a little cleaner and easier to navigate.

NEW RESEARCH AVAILABLE

As promised, this release introduces the first research upgrades for:

  • Freeze Towers
  • Splash Towers
  • Dynamites
  • Claymores

More research options will follow in future updates.

TURRET LIMITS ACTIVATED

The long-awaited turret limits are now live!

Your rank now determines how many turrets you can build. As you climb the ranks, your maximum turret count decreases, encouraging more strategic choices and stronger tower placement.

Less spam.
More strategy.

OTHER FIXES

  • The Management UI now switches to scientific notation for extremely large numbers, as requested by some of our highest-level players.
  • Inbox messages were no longer scrolling correctly since v1.7.4. This has been fixed.
  • Inbox message width and text wrapping have been improved, making long messages much easier to read.

BACKEND IMPROVEMENTS

One of my longest-standing goals was to move game balancing to the backend.

Mission accomplished 🤪

I can now adjust balancing values without needing to release a new version of the game every single time. This allows me to react much faster to feedback and fine-tune the game while keeping updates focused on actual new content.

Have fun defending your base!

CRITICAL BUG FIX
After the new Ads account got approved, it triggered a bug in the code making the App crash on startup. This code was introduced end of January with release 1.3.1 but has been dorment ever since. Found it, fixed it, expedited the approval flow and now you can play your favourite game again :)

It was possible to trick the system over and over again and receive the diamonds as many times as you wanted... Fixed this now, no more cheating :)

BUGFIX! To many turrets = Less power
We had an issue that when to many turrets were build, the efficiency would go down and your DPS would actually tank. Fixed now :)

UI: Introduced sprites!
Turrets and enemies are now build from images/sprites, meaning the game doesn't need to render them every frame anymore!

GoldMines were far to cheap, changing the complete game experience! Per community request, changed the pricing and yield

Permanent Upgrade added: Double rewards on the Bosses
Normally you would get 5 coins and 1 diamond per boss kill, but you can now double this up to 10 coins and 2 diamonds. Savings go up a lot faster!

UI: Permanent Upgrades Menu has been re-ordered
With the new upgrades and the ones that are still to come, there was a need to shuffle things around a bit.

Logic: Code refactor
As preparation for new Game Modes that will be released in the coming weeks, I am changing a lot of logic within the code so it can reuse certain parts easier. Saves a lot of searching and double coding in the future.

Version 1.3.1

Released Jan 28, 2026 15:03
Build 7
Full Changelog

Battery Drain & Game Smoothness
Made some changes to the code to increase the smoothness of the game, especially in the higher waves (See next point).

Cap on enemy count
As part of the smoothness, I implemented some changes on the Spawn logic. First, we cap the amount of enemies at a maximum of 25, but starting wave 25, the increase in HP per enemy goes faster. Also, Bosses now spawn in addition to the standard enemies, not as part of the wave count.

Preparations for Google Admob replacement!
For some reason I got a temporary block from Google Admob (invalid traffic, probably due to testing), so decided to also implement UnityAds as a backup. If one of the two doesn't load, the other will take over. For now only preparation as the account is still pending approval.

UI Updates
Many UI Updates have been done

Upgrade HUD is now optimized to play the game with 1 hand (right handed people). At a later stage an option will be introduced to make it left handed as well :)

Map Select Scene has been updated a little, just to make it look a bit nicer

Leaderboard on the main menu has been updated

Highscores per map
With the new maps, it now shows your highscore per map on the Map Select Scene. Later on I will introduce Leaderboards per map as well.

NEW MAP! SideWinder
The 4th map is now live! SideWinder! Left, right, left... Swirl through the waves!
Practice this one good as soon it will be the base map for a new game mode ;)

Permanent Upgrades
The cost for some of the upgrades were simply not logical, so I made some adjustments here.

Coding Updates
As with any release, some code refactoring has been done again to make it more logic, clean it up and all those kind of things.

Version 1.3

Released Jan 25, 2026 15:03
Build 6
Full Changelog

Release Overlay!
Whenever your game gets updated, you will now see a nice overlay when you start the app telling you exactly what changed. No worries, it will only show once.

Your GameSpeed is now memorized!
When you restart the app or start a new game, you will right away start with the Game Speed you left off with. No more endlessly tapping that button!

Ads work again!
As always with new apps, Google AdMob put a limitation on the viewing of ads. This has now been resolved and ads are starting to flow!

Main Menu changes in preparation for new game modes
With a new Game Mode coming very soon, I already prepared the Main Menu and made some space!

2 Shiny new maps! A major update!
You can now enjoy 2 shiny new maps and more will be released very soon!

Background coding refactoring/logic
I made some heavy duty changes in the code to cope with multiple maps and different game modes. As a result, I made the map processor a lot smarter and more flexible and now I can release new maps in pretty much every release... Expect many more of them..

🐞 Double boss spawn (#222)
When paused at a certain moment, bosses would spawn twice. This has now been fixed.

🐞 Leaderboard update after score (#251)
When you get gameover with highscore, the leaderboard didn't update.

Full Permanent Upgrade Overlay has been upgraded with a nice, category based, tab system. Much more space for many more Upgrades that will arrive soon :)

On my personal wishlist, increase the speed of the game! You now have the option to unlock gamespeed 1.25x, 1.50x and 2.00x.

✨ Added Game Center Leaderboards (#187)
Already added in the background, but now you can actually see your ranking on the Global Leadership boards!

Now that we have some first players that are getting a little further, it also shows that the increase in HP for especially the giants and bosses was maybe a little bit to insane.

🐞 Background Pause issue (#191)
Still had a small little bug hiding when the app went into the background. Found this little bugger now as well :)

🐞 Turret status stayed grey after deselect (#192)
All turrets update their status color after one gets deselected again.

🎨 High score visibility (#172, #188)
Your personal high score is now visible directly in the main menu, making long-term goals more prominent. On top of this, you will notice your score becoming a pulsing green when you hit your high score In-Game!

🎨 Turret UpgradeUI Clarity (#134)
The upgrade interface has been redesigned for better readability and structure, showing current values, next upgrade impact, available slots, and costs in a clearer layout.

🎨 Turret Styling (#166, #182)
Nothing fancy, but the turret now shows the level of upgrades it has and colors based on availability of upgrades. Clarity is key.

🎨 Permanent Upgrades UI design (#175)
With the new Permanent Upgrades, the Permanent Upgrades UI became very much cluttered. Decided to make it a bit more clean with proper text sizing and spacing. Later we will redo it with nice buttons, but for now it is clean and clear again.

🎨 General UI fixes (#133, #193)
Mostly minor little updates on general UI. Nothing fancy, just some stuff that irritated me as the developer and player of the game. (OCD stuff)

⚙️ Better performance under the hood (#190)
Removed unused and duplicate legacy code to keep the game lean and responsive and split the code in separate files for ease of coding.

⚙️ Foundations for GameCenter integration (#150, #189)
Preparations for the Leaderboards has begun! Your Highscore will now be stored both locally as well as in your GameCenter profile!

⚙️ Disabled iPad support for now (#220)
Given the UI is designed for iPhones, not for iPads, I decided to disable the support for iPad for the time being until I get some more information and time to also design specifically for iPads.

⚙️ More balancing tricks
This one you will see pretty much every release... Balancing the base power, upgrade percentages, costs etc to make the gameplay as fair and challenging as possible. (Not to easy, not to hard...)
