The aesthetic is really cute! I kept falling through the first platform though - and even after noodling around in it for a while, I'm still not exactly sure what the goals are.

Pretty good!

A jet pack fuel indicator and being able to look vertical would be nice.

Otherwise a decent platformer.  I wasn't able to get past the block right after the rotating plaform, though.

Note: the checkpoint squares turn beige, breaking the black and white theme.

Also, I like how the executable is named after a different jam going on at the same time.  ;)
