Congrats on completing the jam! I managed to defeat the cave sentry and return to the town. I needed to stop because the controls were cramping my wrist (that's me not you) but a gamepad option could be good for this game.
I have a lot of fun swinging around on the hook - I wish I could've chained hooking in mid air. I didn't really enjoy vertical movement - maybe it needs to be faster and it would be nice if there was a jump. I also had difficulty swinging onto platforms which had a vertical component directly above them. I think the collisions need to be rounded a bit because I would hit the vertical part and then fall down even though the direction key was pressed - would expect to slip in once aligned with the route. Maybe a more horizontal level design than vertical would be more fun.
The cutscene at the beginning was really cool looking! Great job!
