25 players would be too much for a unity game
map maker is cool and all but there would be too many maps to choose from
workshop is cool, like team fortress 2's workshop but i don't think that would fit
35 support? what do you mean? there are ways to find out who the impostor is with 3d
among us itself is good on it's own, doesn't need shaders.
really good ideas, but would be better for another game.
