Never played Messiah, so the idea is very new to me. I dig it a lot, but... It's very jank. It almost hanged up on me until I changed resolution from 4k to something smaller. It was still janky, but playable (up until the platforming part)
I saw a lot of neat features, like the actual cameras on the doors, weapon switching. The AI kinda bugged out on me - it kept shooting at the place where I was when I posessed a new character (they ignored the new character). Shooting wasn't good, maybe it's due to the game running poorly - but it took ages for me to kill someone.
It's a very rough prototype, needs a lot of polish. Platforming messes you up if the game runs poorly.
