Really nice game.
I use a BÉPO keyboard and the key mapping is not on their physical keys but their code key. So in the menu, I have to tap on the key where the "K" letter is (and search for it). However, because we can use arrow keys, no issue in the game itself.
I like the assets and the music. I also like the puzzles. For the platforming part, quite too hard for me not being used to keyboard, but maybe if their is a controller support I would try remaining levels (because we can go there directly without redoing everything, thanks for that).
