From my playing (up to level 8 before I got sick of it), this is what I can tell:
- It's sort of like a flash-based Fetch! but with no limit on time or moves.
Get hit 3x and your candle dies and you lose a life; you have 3 lives.
Foods you collect:





worth 10 points each (AFAIK, they are in the same places each time)
Power-ups:

increases your light radius by 1 (effectively a "heal")

decreases light radius by 1

speed up

slow down
Pushing "loose" tombstones (these are unmarked and have vines on both lower edges) with the spacebar is necessary to access some areas of the maze. Push a tombstone onto an enemy to earn 50pts. You can only push up or down.
also: playing to 1000 points does not give you the avatar (unlike v1.0 of the game)
