You clearly put a lot of time into the mechanics here - I love it. The boost jumps are dope and feel really nice to pull off, especially with the added visual effect. Great music, very appealing graphics - even if they're simple, there's enough polish and flair that it doesn't matter much.
I did call it quits before I beat it, unfortunately. The level that got me was the "wall jump boost to high jump boost" one. I was able to make it to the final jump, but even when I pulled off the high jump, the momentum from the first boost carried me right into the death wall. I'm sure it's beatable, but that's where I ran out of patience.
