I really liked the ambiance (sounds and visuals).
Then I tried to play with a BÉPO keyboard. The keybinding does not depend on the physical position so I took nearly five minutes finding how to go right (it was not even my [S] key). It was the equivalent of [O] in a QWERTY keyboard (I telling you so you can understand how were my hands for the rest of the review). Doing so, I saw that there was lots of keys that made the game go strange, I think there were debugging keys.
The settings for the music did not work, the music was still at the same level. I could change on the computer but having the settings, I think it is a bug.
When I got it working, I could enjoy it. Having platform movement making a boost is really a nice thing. However, it can be punishing, for instance at the start, I can jump between the platforms without any way to fix my mistake:

So maybe a change of the level to reward player instead of punishing them would be really satisfying (but quit complicated to do during a jam).
Then later, I could not advance, the two platforms disappear:

I think I should have gone faster before but don’t really know where/when so quite frustrating.
Overall, I enjoyed the game and ambiance, so thanks for it!
