Hey ! I gave it an other try and I think what got me is that for whatever reason I had trouble hearing the first audio hint when you push the button. Once I got that, the game was super easy to pick up. It's a great gameplay idea and it is beautifully implemented, both technically and artistically. Fantastic contribution. I just wish there was support for the arrow keys as my keyboard doesn't have a qwerty layout and wasd is difficult to use.
Great game !
