The use of the Game Boy Camera to create assets is brilliant!
I was a bit surprised that there wasn’t more to the game when it was over, though. A player making a concerted effort to escape won’t see much variety since the whole map is available right away, giving them the option to follow a direct path to the exit.
An incentive to explore could extend the play time, and some method of obscuring the map could add to the replayability.
Anyway, good work!
