Hey, great job with this game. You did a great job coming up with a low-key metroidvania! Here are some minor bugs I noticed while playing:
Wrench doesn't work with controller (could be my controller)
Frog dialog was mixed around when giving him the 10 bolts
As the head you get soft-locked behind the water fall. I didn't realize you could respawn your body at first.
Great game though, with some good concepts. I'd love to see it expanded to a larger game!
