Turns out what's keeping me from releasing already finished content is "feature creep." I keep wanting to add stuff to the game. I implemented a large-ish change to the core system and now I'm going through each facet to work it in. I think I should stop doing that. lol
The game isn't where I want it to be, mechanic-wise, but that's what sequels are for (if I ever make a RockRobin 2).
