These are the results from the poll. I've decided what I should do early.
Since making a non-Undertale fangame is the top option, I'll finish something else that I started a long time ago (not low effort).
As for Tales of the GLF, I can still make battles. Just send your oc and one of the things you will attack with and I'll make a separate battle for each character (may take some time because I will be working on the non-Undertale fangame mostly). You can have up to 2 phases only, and first come first serve.

I would already have ended the poll, but it won't let me.
