I got the poison upgrade after beating first boss and could not beat the second boss. fun game. also if you spam attack to push the boss against the spikes there's a chance of the boss clipping through
update: I beat the game, wooden boy became much easier after I realized I could kill the canons. also if you spam against the bear you could get launched in the opposite direction so I couldn't see if there was a secret ending if you killed the bear (if its possible)
