so, it's good but:
1- if there is a buton to leave level, indicate it, if not made one, the idea of not having to do all the level to continue is a good idea if we can leave a level, same goes for the option menu, e can't know if the control are good without testing them, and having to quit the game for changing them and restart again to play isn't a good thing.
2- it's a very little thing and maybe this is a choice, but the "door" in level 2 that you need to jump over is a little frustrating, not that it is important but the gameplay is enough to enjoy a speed gameplay when we understand the room but this wall stop us to do so.
it's a good second proto and we see a part of the potential of the idea, good work!
