The game has a lot of variety, which is great! I really appreciate the depth you've added, especially as the game progresses.
A few things could help improve the experience. First, there’s a small typo in the main menu: sciense should be science. Visually, I think a simpler art style might work better, as some parts (like the main menu and buildings) have much more detail compared to the landscape, which creates a bit of an imbalance. It’s also hard to see all the details unless I go fullscreen.
Gameplay-wise, a game speed slider or at least a 2x speed button would be really useful. Camera movement would also help improve visibility. I also noticed a game balance issue, as new enemies take a long time to appear. It might be better to introduce them within the first 2-3 minutes instead of after 7+ minutes to keep players engaged early on. Additionally, the green finger indicator for enemies feels a bit confusing—shouldn’t it be red instead?
I really liked the destroyed tower popup, but it feels incomplete without visual effects (VFX) after tower is destroyed. Also, some of my turrets and soldiers stopped functioning properly—they were stuck shooting in one direction.
Overall, the game has great potential, and with some polish to the balance, visuals, and mechanics, it could feel even more engaging! Keep up the great work!
