Longevity will likely be the only issue facing Underpants Slam. This is not a long game. Each level has a relatively short time limit, and once you’ve played it the first time, you won’t find a lot of variety on subsequent gaming sessions. Of course, the target audience is more likely to be happy simply playing a SpongeBob game, and probably isn’t too hung up on things like variety and replayability.
Licensed games on Microsoft’s Live Arcade service haven’t been all that hot (Shrek ‘n Roll says hi), but Underpants Slam bucks that trend. No, it’s not game of the year, but it’s a solid, playable title that manages to serve the license really well.
