Iron Lung gives you just enough information to allow your imagination to run wild inside your claustrophobic little sub, resulting in a clever little minimalist horror game.

The premise is also very metal in a way that I enjoyed a lot - a convict pressed into a suicide mission in a rusty little can at the bottom of an ocean of blood? That's good stuff.

However, as short as the game is, I don't think the somewhat tedious (intentionally so, to be fair) gameplay was enough to sustain the hour or hour and a half of playtime in this game, leading me to believe it would have been stronger as an even shorter microgame.

So, points for originality and atmosphere, but it overstays its welcome a little too much to be truly great.
