Yep - same comment. Source code on github was what drew me, but I couldn't get it to load. :(

I'm glad you noticed the source code being public. :D
I should've left a readme.md file with build instructions there.
The instructions are actually as simple as install SDL and `make run` on Linux, or setup SDL and include everything in src in one project.
The web-version of the game on itch.io's page does load now.
