My only problem with this game is the difficulty of movement, especially when jumping when in areas with very narrow openings to go through. Other than that, I'm giving the game a 5/5 because it's amusing to talk to all of the different elephants, and the gameplay's pretty good.
Wow, more games need an evolution system like this. Really, the actual environment/inventory of the creature effects its growth, instead of the player going "Oo, this looks cool" and picking the creature. 4/5.
Hm, this probably wouldn't do well as an actual book as a "Choose your own adventure" book, but as a normal novel, a movie or a miniseries (The miniseries maybe being about the different people with the whatever-it's-called earpiece thing) it could possibly be a bestseller. There are few games like this. Instead of other games that make you make everything up on your own, this makes you piece it together and think. 5/5.
Meh, bland music, overused idea, upgrades and controls, facebook is involved, achievements are like jokes, so it's basically achievement unlocked all over again (Oh, you used a basic feature of the game! GOOD FOR YOU!) etc. Not that it wasn't fun, just flawed and unoriginal. A 3/5.
