I love these types of games so this was really great! Really satisfying when you got really strong and just instakilled all the enemies.
The cross hair balance was a bit whack, it felt like some of them were really powerful and some kinda useless. There was also an issue with floating point numbers in the upgrade system making it really difficult to read, and I think I went to negative numbers?
Really enjoyed playing this, one of my favorites this year, great job :D
