What do these symbols mean?

I have never seen anything like this before.

I found this game from searching for dead games on roblox that nobody seems to play. I found this game with weird cryptic symbols that intrigued the hell out of me. It was a snowy baseplate with these two buildings, with a butterfly in between. One was Blue and the other building was pink. I'm assuming this is like a boys room and a girls room or something? I'm not sure, let me know what you think though.

When I entered the boys room, a two minute timer appeared on the bottom left of the screen. In the boys room was a swirly blue symbol on a white background. There were two blue characters on both sides of the room with the default face. In the girls room, it was pretty much the same, however the symbol was a pink heart with two pink characters instead.

User who created this. I found some images in their inventory connecting to the game.
