Cute, but frustrating at times.
Not having a bench to store excess teammates is annoying. You have to trade one to buy a mate for another, then find a replacement. Seeing only the specie and sex of characters in the shop means you might buy an asexual character, wasting your efforts.
Getting a taur round 1 is mandatory. Getting only 2 money per wave feels bad, it's much more fun when you can buy one char per round.
