Review by David Welbourn (originally posted at Baf's Guide)
There's not much to this short game. You're working late at night on a computer project at the campus when you notice that everyone else is frozen in time, except you. Obviously, you must do something about it. On the plus side, it's not difficult: there are only a few puzzles, and only a handful of takeable objects. And there are multiple endings. On the minus side, nothing much gets explained. Apparently, it's up to the player to invent their own backstory for what happened.
