Why not also add a slight VHS effect while looking at the cameras? It feels... So clean, so empty, it needs, like i said, S.P.I.C.E!
Somehow Probably Incredible Cool Effect
Why not add "Impostor Conditions"? (Basically, make an Impostor have a chance of being either deaf or blind, blind wouldn't see crewnates, but would literally track them down with the mere click of a flashlight and deaf don't have access to the map's Crewnate tracking function, but have an ability to temporarily see Crewnates through walls.), some more spice when looking through the cameras (Static effect and some buzzing.), perhaps some actual hands in the characters and the ability to go prone? (In case you can't hide under anything, you can hide from the Imposter that way.) and change the Sprint to a stamina meter?
2.
By the way, sprint regen time and speed depends on the map, 1 word: Balance.
Edit: Oh, and 1's a great one too. I spoke in the comments with Snowbat a while ago, apparently, there's not a lot of singleplayer gamemodes and maps because the game was primarily made for mobile phones, and, as they said, by far the only benefit of the PC port is high texture quality.
I also added a little more stuff.
Ok then! Because i have a (not really) little list...
That's all. Thanks for reading!
