That was cool! The mechanics are engaging, the art and soundtrack is proficient, and there's a lot of charm in the design.
The font is a little awkward; those uppercase lowercase 'I's and 'L's threw me for a moment.
Weirdly enough, this is one of the more difficult games I've played in this jam. While the main shuttle is very hardy, it feels like the rest of the ship is made out of paper; and every lost part is a hefty punishment. It seems at odds with the level design tendencies to throw large crowds of enemies and projectiles into the fray. I think a more gradual degradation of the ship's parts would suit the general design better.
Good work!
[EDIT:] Oh! Another thing: sometimes a lot of sound effects would stack on top of each other and spike the volume. Not egregiously, but it was a bit distracting.
