take a long hard look it has taken you to get 3 chapters of MNM out into the public, then look how long it has taken your to get MNF updates out since 2021, both games suffered significant delays in development, but non so more as MNM. Your only 1 person, and to actually keep attempting to make both games, without significant delays between either, is at best a complete illusion or at worst a delusional.
MNF as ended, there should be no Christmas special until MNF 2 releases some time next year, it's fitting and it's appropriate for the game then, not now, now you have completely killed it off, until you develop the next game. Now you need to pay full time attention on MNM I would also consider bringing in an artists, so you do your work.
