This game has a lot of potencial. This is my feedbak:
=> The progression after rebirth is so much fast. After a few rebirths the speed the you can create humans is insane. In my opinion, it's too much;
=> I didn't tested every alpha upgrade, but when I upgrade to unlock the universe, I became stuck in the screen that it's possible to select the planet. And, after restart the game, if I try to enter the alpha screen, I imediately became stuck again.
