ah, i can help with that. let me try to make a small demo for you on that. also idk if you know how to use the circle pad, so if not then i can easily teach you or give you my demo on using it. but if you do know, ignore that. depending on the game you most likely need bgcollision for blocks that stop/help the player. (again if you know this ignore) this is simple-ish to do. so just ask away..
