The concept is interesting, but I would have liked it more if there was some sort of feedback to notice the controls change (a sound, an animation on the UI?). I had the same issue as many people too : with an AZERTY keyboard, even by switching to a QWERTY preset, there are some keys that I don't have (had to press "ù" for ":" for instance, but I had to test every key to find that :/). That's some minor changes to do to that game though, and the rest was well-made, so, good job!
