Ok so I downloaded this game and played it about 30 mins every night before I would go to bed. It was a lot of fun, very challenging. There are no shortcuts to getting more supplies [teeth, scales, fur] and no in-app purchases. I kind of like that, you cant buy your way to beating the game.
its all text, no pictures no animations. I found out that its for free on the internet, So if you're bored and want to give it a try go for it. Im not sure if it saves your progress though online.
Give it a chance, Dont just play for 5 mins and say "stupid, where are the graphics", give it a good honest try. It bummed me out when I completed it, I wish it could have been longer. A lot of fun.
