Thanks for your comment!
- about the play button, it's a bit strange, maybe it is something about your screen resolution. We made the game for 1920x1080 resolution.
- A and D can be Q and D, depending on your keyboard. We worked with an european keyboard (AZERTY). In USA you have a QWERTY. Sorry we didn't think about that.
- My friend said that with "R" button you can return to the main screen.
Thanks for the feedback! Possibly we will post an updated version later.
