The game is fun but too short. I get that it is only the first chapter...
I also feel that the incentive to get more Essence points is too weak, since no matter how many you get the board doesn't contain enough power ups to beat the S rank hero without grabbing one of the three +1000 end game powerups. It would be cool if you could remove the timer so that you could "Appreciate Your Looks" to 1000/1000...
Also I wish there was a route to beat the army without Skeleton Mages. (but maybe I just haven't figured it out?)
