Think it's been said, but amazing art! The little flurries in the air are a great touch, and great amount of effort put in for a game jam, particularly. I found controlling the rocket a bit unforgiving at first, but nothing I'd object to.
Frame rate is a little chopped for me in browser (Edge), not sure what's causing that or what engine, but it (or something) created a slight lag in the control. I'm gonna try the downloadable version later, but these are picky points, nice job!
