The game's too grindy. Mechanics behind merging 5-6 items are questionable. Why do you still get 2 items when you're merging both 5-6 items? So then, now you're trying to check if the store has that item but it's way too pricey. Eventually you'll run out of space if you're trying to merge certain items. Finally, sometimes there's a weird lag that I always encounter when opening the index feature next to store. Aside from the these concerns, it could've been a nice game.
