Thank you for the insightful comment!
> Further improve the controls, sometimes it is hard to hit an exact spot
That's my constant battle against the library I'm using — out of the box it doesn't support constant moving when you're holding a key, so this is my (3rd version of a) workaround around that limitation. It is hard to hit the sweet spot between "hard to move one place" and "feels laggy".

Thanks for the idea. I'll explore it for future versions.

I haven't thought of that. That will allow for every maze to be solvable — I'll have to see if that would make the first part of the game (stopping at the right time) less interesting/important.
