It’s really very good. It improves over the first game in several areas, mainly with fewer required “paint these building specific colours” missions, and some great 2D platforming sections. The fact that you can save after any checkpoint is a big improvement too, as although it still means that you can still go aaaaages between checkpoints (which is a pain if you want to stop playing, but can’t), you don’t have to do entire levels in one sitting like in the first game. Just as well – some of them took two hours!
The final level was also much easier than the final level in the first game. Still not a complete pushover (and almost a clone of Super Mario Galaxy!), but far less frustrating. The boss, however, was much too easy. Actually, the bosses in general were pretty poor, which most of them actually being the same wheel ‘o turrets over and over.
Still, it was a super happy fun game with blue skies and excellent music, which you just don’t get enough of these days. I mean, I like the greyness of Fallout as much as the next man, but sometimes you just need something with more colours than your eyes can take, and de Blob 2 fits that hole nicely.
