This is one of my favorites, I’ll try to give some advice. First, make sure to buy healing items from the shop, as many as you can. Second, make sure you’re taking advantage of enemy’s weakness. If you do zero damage on an attack make sure to switch it up, it’s usually for a reason. Use jump instead of hammer etc. May want to consider using different characters in different circumstances too. You shouldn’t need to tattle as much as you do. Last, might want to consider swapping badges. I hope these help. Good luck!
