Play the game - Emoticons
:- O (..)_ INTERRED (..)_ :-Q is a short parser-like escape puzzle, coded in emoticons. Waking up in a bedroom, you feel the urge to leave this seemingly unknown place. Getting out isn’t too complicated, there is only one thing you need and all actionable commands per room are provided. It shouldn’t even be possible to fail.
What is most intriguing, is more how the game was made and is running. You actually get to peek at the source code, since you need to copy-paste it in the interpreter - though it doesn’t make much sense as is. I didn’t even know emoticons could be used to store data or be used to code whole games. So that was neat.
