Maze cheats:
You can check if the player presses TAB,RMB or he went out of the screen - check this and restart the level if he did.
Sounds on hittest:
Just try HitTest and PlaySound - google.
PopOut anims:
In old flash player versions you can just make an flame animation, and every frame HitTest it(or in the last frame of flame movie clip) - but i don't think that this is the best way to do it...
Code must be copypastable, it must use the BUTTONS to go through steps, higher framerate please, add some real movement like go forward - UP arrow, turn a bit left - LEFT arrow, with angles it's much better. 1/5
