So 1.14, 1.1.5, 1.1.6 never made it to public release and all their upgrades have been rolled into 1.1.7.
New in this release
LEVEL 1: Constant Fart Fog and the occasional Earthquake.
LEVEL 2: Play level 2 as if you are watching it on a 1980's TV
LEVEL 3: Everything white (Lights, gas jets etc.) now glows!
LEVEL 4: 90's PC pixelated graphics and infrared
LEVEL 5: Now a dimly lit room. You only see what the torch (Flashlight) illuminates
Know issues
Animations of Mutant Poops are skipping frames so their walking is glitching.
Oxygen Tanks on level 4 don’t always appear when they should (even though Mission Control says they are there).
Game Over cut scene sometimes play at the end of successful level completion or when turning very late.
