This is also one of the only projects I've come up with that I haven't totally quit. (Yayyyyyyy) This episode has been in production since November 2016, but due to my low skills, not much progress has been made. (Mostly cuz I suck at LunaLua)
All 7 Koopalings are playable in this episode, each with their own distinctive traits. Of course, with the 5 default slots in SMBX, this means that having 7 characters readily available will require LunaLua. And that means this episode will only be available for SMBX 2.0.
It will require plenty of work to get the characters ready, of course. I'll definitely need to assemble a team. If you want to know how I'll probably set about doing this, first, I'll use Link as a base to create Lemmy, Roy, Morton, Ludwig, and Wendy (custom Iggy and Larry playables have already been made by some people) (though I will recolor them). This is the part I'll definitely need help with. (And I mean a LOT, a f**k-ton). Next, I'll try to get good at LunaLua, and try to clone Link over some of the other playable characters in SMBX 2.0 (6 total). And then, I could call it a day, but I'll add unique abilities to them with LunaLua. (Eh, I'll wait until Demo 2). (If you have a better idea, please suggest it to me).
