Wow, I have been digging this Mario Maker-esque game! Can someone tell me how to switch up sprites? I would really love to do that! Also, is there a translated version?
You must edit the files JUMPXD_BG.GRP and JUMPDX_SP.GRP. Use "Th. GRP editor" (It's posted on smilebasicsource) because it's better than the one that comes by default.
