suggestions in Undertale MULTIPLAYER

i was going to make an essay but the letter limit killed me, so i made a google doc: https://docs.google.com/document/d/1ZkSb5rK2taEETvJ05OYmdhfVqOuI…
Serious suggestion, no joke: add "(not out yet)" to the games title to stop people from constantly asking in the question's channel of this community "how to play the game?" or "where is the game?"
will we be able to make our own attacks in PvP? that would be really interesting. sorry if i say something wrong i'm from brazil and my english is kinda bad
bosses who use different souls like that of kindness, perseverance, etc.

POV: You can play as tf2 characters (I WONDER IF THIS IS A SUGGESTION)
Add Last Breath Sans Phase 2 and 3 as a skin.
make it so you can make your own custom undertale maps for 20 gold and put on a good map leader
i will send you a pic of the idea when i have one
