I too have fallen into the "way to much freaking money" problem. It is a very short but good game. It is sadly lacking in the variety needed to make pvp or endless very interesting. Maybe throw in 2 more evolvable creatures, or a 3rd path on all the current creatures, and another type or two of gem (range or attack speed perhaps).
I'm more or less okay with the tokens creeping virtually everywhere. I am not okay with having to blow tokens to play the game at all. The countdown timer for the next day is horrible, game went from 4/5 for me to 1/5 because of this.
