Such a cool and enjoyable game! It feels very finished and has such good puzzle design! One thing I'd remark is that memorizing where the platforms are when you switch is cool, but it's difficult to eyeball the positions: Maybe adding some detail (not neccessarily a full grid, just some pipes or panels) can help the player to memorize where the platforms are.
That's just nitpicking, though, and for a weekend this is a very nice and finished game!
