The game looks incredibly good, it feels like I'm playing a 3D game, but it's all 2D, that's quite impressive!
It also feels good to just move around the map, that level of polish in a movement system is not something I'm used to in a Jam game! 😲
However, the actual gameplay becomes a little boring after a short period of time. Once you see a strategy that works, you just have to repeat every wave. Maybe if you added more patterns to the AI and more varied enemy attacks would help, but I think that the problem itself is the main concept of "just move, everything else is automatic".
Other than that, I enjoyed your game! I will keep playing from time to time to get to a higher wave hehehe. 😈
