Interesting idea and I really enjoyed this! Maybe there is more level in the future XD
At first I feel a little bit confused because the resolution of the game in my chrome can't show the whole game, and when I make the player jump, the player hit the wood and fell down to lay on the ground XD so I have to restart game
In terms of this I wish you can freeze the rotation of the player object in the inspector so player won't lay down :), and maybe there is some fun relate to when player try to jump, because I try to play music with "Space" button but then I realized that it's a "Enter", it's a little bit difficult while I use mouse and WASD, I have to use another hand to press "Enter" XD
