Summary: As others have noted, there is a timer. You have to complete a level within a certain amount of time. If you fail, you have to go back to the beginning of that level and replay it. This is true even in "easy" mode. There is no manual save. If you play for awhile and have to quit before you complete a level, all progress within that level is lost. The game is inventive, cute and fun, even for adults, but the timer aspect and lack of manual save are irritating.
Summary: I am 31 year old. and no matter age anything.The best games are often those that don't need to bulk out their premise with weak secondary mechanics. THQ's de Blob for playstation 3 the best game in the world, but the idea at its heart is timelessly fun all by itself: colour in. How wonderful to see it back for another try, especially now that it's multi-platform.
