PS: sorry to disturb, but I just tried to compile it, and I don't see how a package fit for repos could be done out of it. it's not finished, the readme contains an error (states about config tweaks you can do in "config.h" but the file there is "config.dev.h" and when you look into it, it looks like you have to setup the config for your monitor in there and I don't know what else).
The git clone command has brought this in less than 3 seconds:
config.def.h config.mk jumanji.c Makefile
config.h jumanji.1 LICENSE README
Then there is no ./configure, so you won't know what is missing if there is something missing in your system. Then make or "make install" returns errors. I am almost sure this application is not ready for anything else than further development... :|
