Great game! I've played lots of games from this jam that randomly adjust things in the environment, but this one is much better because it actually gives you a warning for what's about to happen. Seeing the new gravity direction in the top left, then working out how to use it to my advantage meant I got to solve a fun puzzle every few seconds.
The only change I'd make is to slow down the character a bit. Apple Bro is a little too speedy, making him hard to control at times. Overall though, this is definitely among the best of the games I've played from this jam.
