I love how it is a maze puzzle AND an escape game :)
Very nice to see a puzzle leaderboard game which is also playable and enjoyable! It's already very solid, just need a little more polish. And also has a huge potential to explore other ideas (e.g. already mentioned multiplayer).
Running through all the tiles for the points feel a little tedious, but I don't have a quick solution out of my head and yours give a feel of fair competition.
Good work!
