There's one UX issue that would keep me from playing this game again. When you're in a large maze, backtracking with the arrow keys is very frustrating. Maybe the Backspace key could be used to undo the last move instead of having to navigate back with the arrow keys.
I like the idea - I don’t like the mobile experience. I just spent too many seconds trying to figure out which arrow is down or right in a corn maze. Viewport on mobile is a bit whack. But I like the vibe - just needs some tweaking.
