Held back from greatness
This is a good game that is being held back from greatness. I love grindy rpg games and upgrade systems. The barcode scanning to unlock characters, items and potions is a fun gimmick.
My main problem is that the AP system is an obvious grab for IAP money. The cost of doing something with AP is way too high, especially traveling to instant battle (which without instant battle can take up to 40+ minutes). Maybe if the AP cost and travel time were halved or done away with (since you have already paid for the game) it would become a truly fun and solid game.
