how about you add better graphics and make it 3D in among us 2 and add voiced to the characters.
Other ideas:
If imposters win they do a kill animation and when crewmates win they dance.
Make it so there is “Beginner Mode” where you can join beginner servers like if your on that mode you can have no kill cool down, unlimited sabotage time and choose your speed.
Make there a cool down for reporting body’s cause that will be more challenging.
Add a epic story.
