its great that your sticking with among us 1 and not making a sequel, i have been playing your game a lot and absolutely love the game! but also i have some suggestions.
my idea is to add a medic role. after a crewmate has been attacked by an imposter they have a 30 second bleed out if the bleed out timer runs out they die but the medic can find them and and heal them, after they have been healed a meeting will be called but the injured crewmate cannot talk for one meeting and cant do anything for one round after the meeting until another meeting is called they can then speak and do tasks they will also be stuck in medbay for that round as well the imposter can also finish them off while they are stuck in medbay.
another idea is that imposters can set traps in certain rooms for example on the map skeld there are wires on the floor of electrical what the imposter can do is expose those wires on the floor and a crewmate can be electrocuted once they step on the wires another example is on mira HQ with the vending machine the imposter could poison a certain drink in the vending machine and if its chosen by a crewmate they will become slower and their vision will deplete and the medic cannot help with players that have fallen into a trap but only report it.
this is the last idea but maybe you could add an animation once the imposters or crewmates win this could be added to the computer in the ship where you could choose your animations for example if the imposters win they could show the imposter brandishing a knife i dont know what any of the crewmate win animations would be though.
i absolutely love your game and cant wait to see what comes in the future!
also add a default dance please.
