Destructoid: "If you absolutely positively hate platformers, I'm not so sure you'll enjoy BattleBlock Theater. Unlike Castle Crashers which had the benefit of the simplistic, pick up and play beat 'em up genre, you get more out of BattleBlock the more you're willing to put into it. Positive reinforcement is gained through skill and triumph rather than simply bashing things in mindlessly, so in that regard, the universal appeal is a bit lower than most of Behemoth's older titles.
But as long as you're willing to give it a chance, you'll reap the rewards of a fairly deep, interesting game that was built with a lot of heart. I can't wait to see how Behemoth follows this up, and I hope it doesn't take five years to do it."
