1/5!!! Why? First off it doesnt save your progress...
Secondly this is a buggy chipset. Its annoying to stuck on a tile when you jump and lose because of that. I am really sad. It could be a 5/5...
What do we get if we combine a stupid but funny scenario, multi-form but simple gameplay, great and simple ideas, an evolution system and great music? A masterpiece game, very fun to play game! 5/5!
For patient players like me, i give it a 4/5. Good mechanics. nice idea. But if it was 100% free and not annoying, then and only then it could get a 5/5. Pity.
