This is the worst run game I have ever experienced.
Firstly, lets look at the premise:
Right, so this is a fairly standard mafia game, nothing really special.
A fairly standard mafia game has approximately 20-30% scum in it, with most on one faction. Not 5 factions each with a kill ability.
In other words, you clearly devised this game with the intention of deceiving the players, by lying to them in the very premise of the game, meaning people were not signing up for what they were given.
Leaving that aside, lets look at how you balanced these 5 factions to make sure that the game would have an element of skill in it, that factions would be unlikely to be immediately wiped out....
You didn't.
If I was to make a game like this, I would have distributed a one shot kill immunity to every SK (meaning no faction eliminated overnight), given the scum a couple of reasonably powerful roles (Devil, Roleblocker, Untargetable etc.) and made each town quite powerful too (Baner, Tracker, Vig, Innocent Child etc.).
Thus there would've still been a highly random game, but the interactions between PR could've kept it fun and interesting.
Instead, we got the debacle we have, with Town winning on luck, and SK winning without casting a vote.
And lets not mention the deadline issues...
