Love it! Possibly my favourite jam entry.
Fun to explore. Looking out for the tiles you can pass through is fun and just subtle enough. Lots of powerups. The abilities are all really clever and a good fit for the game. The minimal jetpack gauge is great. The mini-challenges all make good use of your abilities. The level teaches you slowly about how to use the abilities before you need them for something really challenging. The way the boss combines use of bouncing bullets with the jetpack for a kind of bullet hell experience was really satisfying.
And I thought the way the small amount of text appears in the corner to tell a bit of a story was really classy and injected a lot of character.
The only points of criticism I have are that the music can get repetitive, and the platforming around spikes can sometimes feel a bit sloppy (maybe because of their collision size, or maybe because the jumping/hovering is not quite precise enough for some of the challenges).
Great job!
