First of all we had not too long ago a update for the new coding which was cleaning other peoples mess, now we doing everything again to make it Full HD, so that being sayed, you can indeed split into parts, first coding the minigames into full hd, then handle the backgrounds which is the longest process one and so on, it would be split by sections sorta say then making x content into Full hd then other content, cause that would only fck up everything, right its not even worth trying to make into parts cause we close to the end of it, but wouldnt be surprised after it in 2 or 3 years having another coding update.
Now has for the animation batch or tiny content, you really think the Tech update will be finished in the next 2-3 months when the progress barely moves?, only with good pace and luck they will be able to finish it, believe it or not if in 2 months there is no tech update end yet you will have another batch or tiny content story, cause they have to present something to keep the patreons happy.
