Unfortunately this game is really hard to play if you do not have a Qwerty keyboard. Please use Unity's Horizontal/vertical axis input system next time.
It's a cute idea really, and I'm undecided whether the gridlocked movement without a stationary turn is great or terrible. It is hard to tell how much you move in the dark though, perhaps it would've been better to keep the map stationary and only move the player character. This might have turned the difficulty down a bit too.
I didn't like the background music unfortunately. The visibility toggle is also a bit hard on the eyes. Maybe giving players just a fraction of a second more time to see everything would be better and strain eyes less.
