Fantastic entry! Wow, really fun game you put together here. First off, I love the art. Really gives off the hand draw kinda vibe, and the animations are super fitting. Everything is nice and juicy. The gameplay loop is very satisfying, I loved prodding at weaker sides of the map with an army of skeles to shoot away the buildings. Only downside is the recharge time, I think this game would really benefit from an increase in difficulty along with an increase in resource generation to really let the player continue the onslaught.
Game is a ton of fun, phenomenal entry.
PS Nice to see a fellow Godot user, just curious did you use 3 or 4 to make the game?
