@Ronflaix https://www.doomworld.com/idgames/levels/doom/Ports/j-l/kewk pretty sure it's this one :D "Kill 'em with Kindness". Doesn't actually contain any killing if I recall! I mean from a code/mechanical standpoint it does, sort of, but it replaces the death animations with happy dog animations and happy flower animations instead. and it's non violent :D
@Ronflaix I've seen that one too ^^ I think the original was based off Wolfenstein 3d's engine?? Or am I thinking of Chex Quest...I forget.
Either way yeah, I mean I'm not too jazzed with the religious element but I'm all for non-violent cute and wholesome mods of very violent games ^^
