Another gameplay demo video recorded retro style with ZDoom LE (a ZDoom version for legacy machines) and GZDoom 1.3.17. Note that the game looks much better in OpenGL due to the palette conversion in software, also i used the 320x240 resolution in ZDoom. The mod runs fine on GZDoom 3.1.0 and Zandronum 2.1.2 and will be released later today.
