The game was quite challenging, especially with the camera being so close. Coupled with the absence of background and the fast movement of the platforms, it was hard sometime to visualise movements. I was able to go pretty far, but was stopped by a monster that took me by surprise!
It still was enjoyable. 2D platformers are hard to make right, and the physics here is at least pretty efficient. I'm sure that with respawn or some checkpoints, I could have managed to reach the end!
Also I found some kind of dash on the shift key? Not sure how it's supposed to work, but it somehow helped me pass a larger jump at some point. ^^
