For me, this was the most interesting game of the jam! I spent 30-40 minutes on it and ended up leveling up almost completely and killing the final boss. I really liked the attack mechanics, the Thunderer's charging, and the leveling tree. But I would have liked to hear music in the game, and also if I could zoom in on the tree using the mouse wheel.
Yeah unfortunately I ran out of time (and effort) to make music. As for zooming, TIC-80 has a hard coded screen resolution of 240x136, so the best I could have done is double-scale.
