This was a pretty enjoyable game, with a neat concept.
Took me a few attempts to get through the game (after reaching an effective softlock with the couch ship stuck in a death spiral as it spun faster and faster out of control with the buoyancy fluctuating rapidly between going upwards and downwards (mostly downwards)…) eventually I just decided to avoid adding couches just to keep the ship balanced.
Still, very clean presentation, gave Skelly a pirate outfit, and managed to go all the way up to space!
Nice work!
