Hi matt,
This is effectively a “port” of JP’s WotM. Since WoTM was exclusive to GZDoom, and WadSmoosh, I came around to the idea of porting it to other source ports, that is to say most others, mainly near vanilla ones, such as DSDA, Woof!, and even Eternity.
It still works with GZDoom, although ironically it is the port I had more bugs initially.
It is completely standalone, you build it the same way as WS, but instead of an IWAD for GZDoom, you are building a PWAD for most source ports (at least the ones that support some form of MAPINFO). The instructions are on the GitHub page.
