There are so many among us games making it unoriginal and there is already a game called Imposter of among us.
90% of the community will say "Oh It’s just an Among Us game. It’s really too similar to the Among us game, Use something else than Crewmate and name impostor to something else. Among us is a bit cartoony so make sure your style is original. I don’t think you should make something really close to the Skeld and the Among us lobby, maybe a ship that might give people an idea of the Skeld when they think about it for a bit. Point is that you need to make a bigger twist, like a major one. I’m kind of tired of games that took too much “inspiration” from Among us
My answer is don’t do it the concept is already a ripoff of the actual game among us and it has lots of elements from murder mystery games. Also, there is a game already based on among us with basically the exact same name as your idea.
Don’t do it. Become original.
