The graphics are stunning, but the keys to move the player are bad, "AWSD" to move the player would be better or you can give us an option to change it. The puzzle mechanism is really nice, congrats!
Sorry about the controls, we developped it with/for a French keyboard, and it seems that our WASD compatibility didn't export. You can also play with a controller, which is the intended experience.
I've updated the build and fixed it, thanks for the feedback!
