Arduino Pocket Game Console + A-Maze - Maze Game

The project I want to share with you today is Arduino maze game, which became a pocket console as capable as Arduboy and similar Arduino based consoles. It can be flashed with my (or your) future games thanks to exposed ICSP header.
I had an idea few months ago to build a maze game on Arduino, but without hard-coded set of mazes. It should be able to generate a new maze for each level you are playing, so you never see the same maze again :)
Code I used as a starting point i took by SANUKI UDON and his project HOW TO MAKE A MAZE GENERATOR USING ATTINY13A
