Just your average collapse...
The graphics are good, and are definitely more interesting than squares, cubes, or smiley faces so you get points for that. Sound was good too. Overall, though I wasn't really impressed. Don't get me wrong, it's a great game, but with all the other collapse-esque games out there, it needs something to set it apart and make it better than the rest.
A few suggestions, first the game needs instructions. I know this game isn't rocket science but there's bound to be someone who has never played a version of collapse before and won't know what to do. Plus I had no idea what the purpose of the tiger-stripe eggs were. I just thought they were some kind of rare dinosaur that would take forever to get three side by side. I accidently clicked on one and figured it out. It's really just professional to include instructions.
And one last thing. When the game is tallying up the score and the number of empty spaces, it's a bit slow. Not slow enough that you can fall asleep, but slow enough to irritate. A bipass feature would be nice, or if it could just count faster so it would only take a few seconds.
Overall, a nice game worth playing if you have nothing to do.
