if i may suggest something...
1. option for role preferences would be nice some people like being impostor and some prefer to be crew so it would be nice to choose prefernce that would increase chance to be impostor or crewmate - for example i love being impostor yet 90% of the time i get crewmate which gets boring as time passes
2. maybe (and just maybe) some kind of leaving penalty :s i know... its also game for mobiles so people can for example play in situations when they dont have a lot of time or something but lets be honest they should just pick better time to play instead of leaving team... people leave a lot mostly when they get killed or caught as impostor or didnt get role they wanted (i mean leaving 2secs after start so i guess thats the reason) which is annoying and can lead to game over for their team
Anyway great game i just finished playing for today which took like 10 hours becouse ive started playing at 8pm wanted to play for like 2-3h and before i realized it was 6am xDDD
