I know this is a ragegame, but I'd argue its really hard to impossible. I didn't come further than the 2nd level sadly. What I like is that the theme has been implemented in a really creative and new way, I have not seen before. Maybe it would be better if there is a buffer, so you can stand roughly for the same time in the same place? To make everything precise to the frame, it is too hard. At least for me haha.
At one point I also bugged myself into the ground, but thats of course just a minor thing. The controls were snappy and easy to understand, just as the mechanic itself. I instantly knew what to do and didnt need a long tutorial! I like the music, and also wanna add that I really see potential for the game, if you make it a bit easier :)
Thank you for you very constructive feedback. There is buffer in time for exemple, I really try to finish all levels in while I was developping it! For the second level, here is the best path to take. And for diffuculty I thought that developper may want some high difficulty, they may be harcore gamers haha. For the bug, it can ruin the experience I'm sorry I could not fix it! And thank you again
