Esc

Lore : 

You find yourself in an unusual place. You don't know how you got here or how to escape, but all you know is that you have a swinging device that you some how can't drop and an urge to swing your way to the top of the building....

Yes, pressing escape to exit the game is the "iconic" feature.

Features:

• esc to exit
• multiplayer (I can't help you with this)
• swinging
• an itch.io page

and more... I think.
