I barely know what a chord is, the credits for the music are in the game's description.
I definitely messed up the gravity on the player, that was pretty evident when this was played on stream, so the difficulty is more so my fault (which is unfortunate, since it would have been so easy to change, oh well).
In level 3, did you get stuck going up the cave to the left? Since you can essentially use the logs to build stairs and lean it against the wall.
Thanks for playing!
