Saw this for free and decided to try it out.
Basically, it simulates using MSN Messenger from 2002-2006, talking to a high school friend. Won't say much more, but whoever lived those years waiting forever 'till that special someone went online, will get a hard load of melancholy from this. It has little nice details, like using profile picture icons and reading other people's bio descriptions, with those song lyrics they written there to give indirect messages make them prettier.

Short game, with some cool hidden achievements for the achievement showcase (there are guides on how to unlock them). Simple, but then again, if you are kinda oldie it will get to you.
