Cute little game about discovery. I liked the novelty of the concept of a platformer where your default jump height is sufficient to kill you. Discovering the mechanics of the different jump-heights along the way was fun and I liked how it made me re-contextualize rooms and understand puzzles that seemed impossible before. The gravity flip reveal and subsequent run to the 29th was a really cool finale to the game and it actually made me think a little as well.
The layouts of the rooms were all thought out to be traversed both right-side-up and upside-down, but none of them made it so obvious I had any idea. The option to view a grid to plan out a route was also a nice touch. The only time I really got stuck it was because I was being a moron for 20 minutes. Definitely worth a play.
Fun game, very short and sweet.
