After 20 minutes of playing I made it to the rooftops. This game has a good bit of personality and you made me want to play more. Maybe I'll give it another go to finish it later.
One thing that was not really obvious to me was the physical interaction of the rules box.
Other thing that made loose a bit of time was in the level where you have to dash over a long pit, the walljump wasn't really intuitive for me. When I had to walljump to direction reversal I always wanted to change direction before jumping and making me stop the wallslide and fall.
