Cool game! I was able to get it to compile on Mac, lmk if you'd be interested in having me upload a build or share the changes on GitHub or something
Yeah, here's the repo! https://github.com/japhib/impact_7drl_mac
If you look at the commits, the "initial commit" is the source as it initially was, just after downloading (just the src folder). Then the next commit "Fix build for Mac" has all my changes. Mostly just changing a few #includes and then adding a CMake build script.
