Press the green flag to start, and use the arrow keys to move. You may also want to fullscreen so that you can see easier. If you hit the walls you "Hits" against you and you get sent back to start. If you get 30 "Hits" then you lose the game. If you successfully complete one level (by getting to the green circle) then you go to the next level. If you complete that level too then you win the game.Great job if you do by the way. It's pretty hard to complete. ENJOY! :)
This was an assignment for my Online G3 Class. (Sorry I took your pun HG2) It is possible to complete these mazes. I've done it (without cheating).
