Very interesting and cool concept! I mean, I would have just told most of these commenters to touch grass tho. I thought I was aboutta get jump scared before finishing, I got a brief doki doki literature club flashback
As for feedback, a volume setting would be nice. Maybe a bit of an explanation on what to do when you start, like two matching comments drop right away and the colors are flashing/highlighted so the player gets the idea to connect them right off the bat
