De Blob is a sweet coloring adventure game you'll get sucked into.
The beginning is a little slow because of the tutorial stuff, but once you get into it- it is a lot of fun and will keep you busy for a while. I definitely give this a thumbs up and would recommend it to my friends. I can't wait to play one of my friends in the blob party mode which looks like a lot of fun.
All-in-all a cool concept and a fun game.
