Time Rift

so i'm not too sure about this but... the first time i went through rumbi factory (nyakuza metro's purple time rift) i noticed a puddle of red liquid on floor 2. here's some screenshots:

i ended up having a discussion about this on an upload of rumbi factory's BGM on soundcloud and i just wanted to see what you guys think
