A nice solid maze game. Changing the look of the maze helps keep the game looking fresh. I might recommend increasing the movement speed for people with little patience.
To start off it could really use some music to keep people entertained while they are playing, also a timer for levels and score system so it challenges people to get better scores. a back to menu button if a timer is made to get a better score and redo levels that have been done. maybe an enemy that walks a certain pattern so you have to avoid causing it to be more challenging w/o these things its simple and doesnt require skill. hope these ideas help you, good luck :)
It got boring very quick, it needs music for a start also you could give it a storyline, you could make different blocks and make a upgrade store of some tipe, it was good but it has room for improvement.
It's just another maze game. Nothing different, nothing fun.
