So first off, love the sound effects, I've never had more fun being berated by a monotone voice in a game before.
However, I do think the game is currently a little too hard, your jump is higher than the gap between the blocks so there is a very small zone to jump where you can actually survive, and currently you can just go infinitely up or down without anything stopping you.
Either way given you say your proper game broke this definitely isn't bad for a backup!
