"CLOSED IN" is an abstract platformer game in which you are falling down a shaft and find yourself in some kind of abbandoned underground bunker... Explore it... Try to survive!
Find keycards to upgrade your ability to open locked doors.
Oh and death is perma-death! So you have to restart when your health bar is empty!
This is a new special newgrounds version of the 2009 game. It was exclusivly on Kongregate, but I decided to finally break that up, so it can be also on NG.
The changes are:
-Monsters do less damage
-Removed the instant kill on the second ventilator
-Redesigned the "Mindf*ck Room"
