Honest answer? No. Mostly because of the mediocre variance in the soundtrack. There are only 4 full-length worlds/albums and one bonus level. Great gameplay and art design, but the limited levels and musical repertoire really hurts it.
Oh, and the levels are randomly generated, as are the enemies. So sometimes you might have runs where you're tiptoeing through the tulips with nary a foe and others where there's half a dozen dudes with machine guns and NO COVER.
At most, it's a 9.99 title, but if I could do it over, I wouldn't have parted with more than 5 bucks for it.
