if you upgrade map to be smaller, when the boxes go to the top they just keep falling over the sides and delays the prestige. Annoying as hell. Takes extra 10-15s to prestige.
Pretty good game, didn't expect last boss to be so hard, but luckily I had plenty of materials to make plenty of defensive and offensive potions + health potions. Had to pull back once to reapply buffs and heal up more. But yeah, maintaining 20+ MP regen made the game really easy.
