Hi, your game is too difficult. I only made it to wave 2.
The enemies are just as fast as the player. Because of this, you can't shoot them, since you can't build up range and you end up shooting wherever you're looking.
It would be better if the player automatically targeted enemies and shot in that direction. That would be fairer.
I couldn't even get to the room building stage. I was just happy I could chop down a tree. Q/E or just one button to switch weapons would be better for me.
The idea is still good, though. It just needs some balancing to be playable.
