Unfortunately the core loop wasn’t finished until the last few hours of the jam (learning Godot and making a game in 5 days was perhaps a bit too much for me), so balance did kinda go out the window lol. You probably can’t survive past wave 10 though. By then it’ll be spawning 10 heroes a second, and you’ll have 500 to go through. Odds are you’ll eventually get to a chain of barbarians (axe dudes) and then die to them.
That all said, even though the game is easy, the reception has been pretty good. I think I’ll remake the project (for cleaner code and project structure) and continue working on it.
