Very fun game. Controls took me a minute to get used (maybe a bit floaty), when I got them I really enjoyed the platforming. Loved the idea with the rotating level- must have been hard to design levels that work from four sides.
The only downside was the graphics. Lots of people will look at it and figure it's another "jumping-square-I-my-first-unity-project" kind of game, and not really give it a try. Maybe consider using some free assets, paid asset pack, or getting a graphics guy (I've done all of the above with varying results).
Had lots of fun- keep up the good work!
