This is very similar to my game!
I really like the condition of failure in this game as opposed to mine--a timer. It forces you to know each level very well, further enforcing the Failure is Progress theme. I also like how you can, just faintly, see parts of the level you uncovered. I turned up the brightness on my computer and used this to my advantage. But as everyone else has said, the jump is very inconsistent and it led to a lot of unfair deaths. Otherwise, the art and music fit the mood, and overall, I had a fun time.
