Looks great so far, but I'm noticing it's a little awkward the game requires both hands on keyboard but then also requires mouse to be used before/after so I think everything would be soother if you could just keep using the keyboard. Understandable some things would still be using the mouse, but it might be nice just to have the Enter key go through the motions to get to the next level.
We hear you, your idea does make sens.
