A slightly updated version, 1.16 is now available. A map layout was reworked to allow easier backtracking and make those 3 screens more interesting. Also, a physical release of Machine Cave is in the works!
Version 1.16 had a tiny little error in it's code, so I made some changes. This new version 1.18 has another revised map, a door skip was fixed and the title screen changes color now!
