Also I like how even items are changing their properties, like there was a toy knife and empty gun, then gun becomes a toy, so there could be Handless knife or worn knife(just like worn dagger in UT). It's used, but real(Gun is empty, but that doesn't means it's not a damn real weapon).
I think this is somehow sans with PTSD from the other sanses, because in their universes chara is a relentless and ruthless murderer,but in his she's just some random kid
