That's really cool. I think you should try to play it backwards, it sounds like a recording being played backwards, and someone was saying stuff.
Anyways it's awesome and actually I think it would be really hard to find so... you go!!
I just tried doing that but it still doesn't make sense so idk
Edit: Actually in the regular version of the video you can make out some of the words it's just really hard to understand. I made out things like "Howdy! I'm Flowey the flower!" and "You know what's going on here don't you?" Which are both lines Flowey says in Undertale. Interesting...
Edit Edit: I also made out things like "Do you think this is funny?" and "Do you think I'm scared of you?"
Edit Edit Edit: "Do you think you can save her?" "Do you think you can make me better?"
Edit Edit Edit Edit: I also think it said something about being in the underworld. Yep idk what's happening but it's neat
These are all Flowy's lines... That actually makes a lot of sense, because you find the video when you click a flower silhouette.
I wonder what that could mean, though...
