Yes, it is too ambitious and I'm cutting corners to get a MVP deliverable by the end of the jam (for barebones, I think I'm about halfway, slightly below it). I'm using RPG Maker MV.
As for why, cause that's the only RPG Maker I actually own right now. Personal budget is pretty tight and this purchase is from last year or something. I'm hoping to raise some small supports, if Allah wills, to help further development.
