ugh...
did you play the game at all? the movement to the top and bottom of the battle is very stiff. Battles are waaay too long. The battle music reloops about every 10 seconds through a 5 minute battle. Upgrades cost so much compared to what you get from battles. Level 4 is absolutely impossible. After you buy the second attack, theres a bug where you lose money from battles instead of gaining it, and you can't buy any more upgrades.
All in all, I really tried to play this game because I liked the general concept, but this game is simply unplayable.
