Enigmo is a lot of fun, and is very addicting. I wished the price was a little less, but I'm still very happy I purchased it. This is probably my favorite game I've downloaded so far.
Cro-mag...I haven't played. However, since Crash got better reviews...I went that route. Check out Crash Bandicoot. Everything about the game is pretty good! My only complaint, is that there are only 12 unique levels.
