*sad*
I pre-ordered because it was not Windows only...maybe Ren'py is more easy to use than Unity and it's free.
I would be happy just with a Visual Novel running on everything ^^
A plain VN without animation but with the same plot and characters would be great!
Or you are going to refund people without Windows as main OS?
BTW,If you use RPG Maker MV,you can make the game for Mac and Linux too :)
