The game is really fun in general, well done! Really enjoyed the few levels I tried out.
However I found a few of the below things a bit too annoying to complete the game, as it made some of the later levels a bit too unforgiving to tiny mistakes:
- The jump timing feels punishing - particularly it's easy to miss jumping off the edge - consider having a look at this video:

- the white/grey/black colors are way too similar, it's definitely not obvious at start, and while you get used to it, if someone doesn't see the difference well it could be annoying. I'd recommend the contrast MUCH better - as right now they all appear as some sort of gre
- when switching color that "change animation" over the whole screen is annoying and unneeded as in some parts requires you to stop because you can't see for a second. It can stay, but it should be faster or not block the view as much
