Ahh, yeah, that's a typo. It ought to be "tsukundere run -L". Btw. since you're coming from onsen-ningyo, I should warn you that this one requires Tsukundere 0.4.x, which also means bumping Guile-SDL2 to 0.7.x and installing libpango1.0-dev before running Tsukundere's configure sequence.
That being said, you should encounter less bugs on this one (though tbf. I haven't evaluated all the bugs that come from "side-by-side" installations on traditional distros).
