The random level generation doesn’t seem to be working as intended. For the first two worlds (the crystal caves and ice caves), the whole level spawns above me, and there’s just a straight line to the finish.
Since the hand-crafted levels are downloaded files, I’m not going to be testing them at this time, so the random generation is the only thing I’ve seen (which will likely be true for most people that try the game).
It’s rather annoying that dying makes control swap to another cube, since this usually means that messing up with one cube will kill another one, making me lose any progress I had in the harder levels.
The game’s thumbnail looks like it might be AI generated, and the little bit of text saying “Remix on Berrry” indicates you used an AI tool for creating some amount of the game. This jam states in the rules that No AI is allowed.
