One word: logistics nightmare
The game, at its core, is fun, but once the multiplayer aspect is thrown in, everything goes to s*#! so to speak. With each player controlling one character, and most puzzles requiring many of the same tactics to pass, either the game either becomes repetitively boring, or incredibly hard, taking multiple tries and retries and sometimes being impossible short of player's keyboard (okay, maybe it was just because our warrior kept falling off every platform).
The game's single player aspect might be fun enough to play on your laptop when you're bored, though.
