This game was really nice and an interesting take on the theme. The music was pretty good, but the gameplay felt really difficult to me.
I would suggest making the obstacles a bit smaller to allow players to pass through a bit more easier. I saw myself struggling for about 2 minutes getting through the beginning part of the game.
Also, I feel you should also add some feedback to the obstacles to give players a sense of when to move and when to wait.
Some checkpoints would of been nice as well. After struggling to complete the obstacles, I died and had to start over, which would of made me spend a whole lot of time trying to beat it when there are other games to try out at the same time.
Sorry if this seems a bit harsh, I just wanted to give some feedback to how the game could be improved alot. The idea behind it was pretty good though.
