Kinda weird game, but that makes it challenging.
The physics are my main complaint. The air movement goes slowing down until you press another key, then it goes full speed again. Because of this, I dodged most of the obstacles by jumping out of the level then coming back.
The graphics are just Unity geometric shapes. Nice job with the music, but I think it lacked sound effects.
I don't know what part is meant to be "unexpected".
Overall, the physics makes it a bit frustrating, but I enjoyed playing it.
