another shop you could add is a quest shop, now these quests are repeatable. like kill 5 slime, so you kill 5 slime, and it will check if you have an active quest, if you do and you are completing the task it will add whatever the task is to the counter, so it would add 1 to the counter on the quest if you killed the slime, and once it reaches the counters goal, it will check if the number is greater than the counter and then set it to the number it's supposed to be if it is. and then stop checking for it, the once you claim it you will be rewarded the set XP and gold it told you would get, then you would activate another quest and then continue the cycle, it will help with game progression, so it isn't spent fighting monsters the entire time.
