Chapter 2 fix: Olya's messages now arrive on time instead of piling up until the end of the chapter. Professor's timed replies give you enough time to actually read them. Thanks for the report!
Only the current version so far โ new entries appear as the game ships updates.
Two months ago he texted "i got bored" โ and left. Now he's typing.
"hey"
You've got a few seconds:
๐ฌ "Hey" โ find out why he's back
๐ง "Wrong number" โ let him see you couldn't care less
๐คซ Say nothing โ leave him on read. That's an answer too
Whatever you pick, the story truly changes. Not just "a different line in reply" โ different scenes, different relationships, a different ending. ChatSim is an interactive chat story where everyone you text acts like a real person: they notice your tone, remember what you said last week, get hurt, disappear, come back.
And the ex is only the first of seven.
๐ The professor whose messages stopped being about class a while ago
๐ The campus crush who suddenly texted you back
๐ฎ An unknown number at 11:58 pm: "hey. you don't know me. i mean you do but you don't"
๐ A contact your best friend shared: "OLYA'S BF๐". Step into someone else's relationship
๐ฅ "I know you have a boyfriend. You said it, I heard it. I'm texting you anyway"
๐ Your childhood best friend: "I love you. But I can't forgive you"
Seven stories โ and not all of them are about romance: one is about a friendship worth saving, another about a past that texted first. And Olya, your best friend, is always around: she notices everything and asks straight out. You can lie to her. She won't let you forget you did.
WHAT YOU'LL FEEL
๐ข Whiplash like the real thing: "i hate you" โ and a minute later, "can i call you?"
๐ That frozen stare at "typingโฆ" when you know everything is about to be decided
๐ The weight of every word: a warm reply and a cold one lead to different scenes โ and different endings
๐ฑ You can close the game anytime, progress saves itself. Getting the chat out of your head is harder
He's still typing. What do you reply?
