This game is very similar to Sokoban/CyberBox/etc, push boxes around, try not to trap yourself or get stuck. In this particular game, you are a green blob who needs to grab items, get the key, and go to the exit. You have a limited number of moves to do this, this feature makes the game extremely hard. The items are drugs or drug-related items; this game is designed to fight against substance abuse in a light-hearted fashion.
Only download this if you like very hard puzzle games that require lots of patience.
