Underwater is on multiple levels but, only in one world. Plus there is some under water boss action that should be pretty fun.
Will it have iCloud savegame sync? I really like this feature in Scribblenauts. Would be awesome to have it in Paper Monsters.
Yes, Paper Monsters does have iCloud save. We've made it to be as simple as possible. If you have iCloud enabled just play on any of your devices and your game will always be right where you left off.
The question now becomes, why have you not released this yet!!! Arghhhh, it pains me not having this on my phone.
