I think that the game could benefit from a better system for organizing your beasts. The ability to sort, perhaps? Anything that would help keep track of what you've got.
I like the game mechanics, but as others have said, the energy situation is a little silly. Shorter energy regeneration is needed. It would also be good if energy refilled at fame/football level ups.
It would be great if there were a way to check which moonheads you've beat... I'm down to the last one and have gone back over every planet more than once. I still can't find it and it's getting pretty frustrating.
Why is the Epic arena singleton? I like the idea of a 60 card deck, with more life to force a longer game, but singleton makes things feel pretty random. You can't really build a strategic deck.
For the Angel General, I'm not convinced a 3/3 Angel for 5 mana is really better than a 2/2 Angel for 3 mana. In pvp, it's pretty hard to get 5 mana. I've found being able to pump out the weaker Angels to be much, much more useful.
The current rating system we use is called ELO, it needs to add/reduce rating for every battle. We are working on sorting this issue out so stay tuned for future news.
I agree with NICofMay
It should cost something to switch out players beyond the risk of intercept. Otherwise you spend too much time guessing what the other play is going to do.
Buggy. Balls sometimes appear randomly out of the top left corner. Also, badges are buggy. Can't get the medium badge to accept that I've got past the first level...

We've heard a few people affected by this bug. We're working on it and hope to have a fix soon. Thanks for playing :)
