The game was super duper easy to understand when I started, and I made the mistake of not buying anything in the shop to defeat the last level but it is a really good concept for an official game.
Since you used godot, may you please tell me how you exported your game and if you don't mind, how you made your game in 2 DAYS too!! (I ask this bcoz I totally failed my game :( i'm just looking for fellow godot users for advice)
