I don't think a 1:1 port is possible, since GameMaker never had a Wii U or 3DS export option, so the game would have to be remade from ground up, but it really is a good idea, maybe it will happen someday

"if you yeally want it, youd do it yourself instead of begging." I have no programming knowledge yet im trying to demake castle crashers for the 3ds. No hate, good luck, and also. if someone wanted to make deltarune like that theyd need to make the whole game from scratch.

ahhhh......i hope this is real!
