How would I make a among us game?

Now this is a question I had for a long time…

How would I be able to make a among us game?

(I need some help, or if anyone can warn me about something) I seen the game imposter and I liked it.

I also tried searching stuff up…

note: I have did some scripting stuff. but I can’t figure out how to make the imposter have kill and sabotage and stuff. the hard parts for me are the tasks, tasks bar etc.

the video is above is what I wanna do.
