Simple and engaging game
I liked it. It kept me entertained for a few minutes. I can't see that there's replayability value, but heck its a little game.
I did like the Yeti, that caught my eye.
What could be cool would be to make the walls more interesting. Throw some easter eggs in there. Give people a reason to explore while trying to figure out the maze. Then if you toss in lives and checkpoints then maybe you have more reason to play again.
