I would wager that more platforms than just DragonFly need the original
unpatched code for this to build. I would like to have the patch conditional
on __NetBSD__, but because it's been patched like this so long, I'm leaving
the NetBSDism as the default and the original code switched on with
__DragonFly__. Other platforms will have to tag on as they get identified.
Hex-a-Hop is a hexagonal tile-based puzzle game with one simple
goal: destroy all green tiles! There are infinite undos and no time
limits -- you just have to find a way to destroy all the green
tiles and step on a safe tile at the end.
