From Gamertell's review:
"Scribblenauts is an impressive game and there's nothing else like it out there. It's a lot of fun to play and it does make you think. However, it isn't the life-changing experience that was lauded before its official release. It is a good game, with a lot of entertainment and replay value, but its not quite perfect. It's a good start though, and hopefully there'll be a sequel that will fix all of the Scribblenauts imperfections."
