The Good
As a cartoonish, stealth game it's quite fun and I can imagine it'd be fun playing with a partner, coming up with double-team strategies to beat the security guards. You could say it's a "family game", the guns seem to be loaded with rubber bullets and everybody gets up again after they're shot. I like having to grab all the loot and get to the blimp on the roof to escape and it's fun knocking out a guard by shoving open the door in their face :)

The music is good too, a funky John Baker, Toejam & Earl style soundtrack.

The Bad
So you can win this game by running through the guards and ignoring all the stealth programming. Sniping or sneaking past the enemy is a more satisfying challenge (your gun fires at a slow rate, perhaps to encourage careful shooting), but if your time runs out, all your loot gets returned to its position and you start the stage again. I don't think the stealth concept has been put into practice all that well, it can sometimes seem easier to just run around firing your gun like any other run 'n gun platformer, getting shot and then taking advantage of the temporary invulnerability to leave behind the obstacle that brought you down, costing lives, but saving time. I should also note that using a continue after game over will not reset the stage you're on, you'll resume as you normally would after losing a life, but your clock will be reset i.e you get a time extension.

The Bottom Line
I suppose the game is really meant to be played with a partner as playing alone gives you only half a screen. But it's a stealth game as well as a co-operative game and if you learn how to play the stealth system right at the start, it can be fun, otherwise it'll seem like a pretty horribly playing platformer.
