My guys getting hit and stopping work was probably a big part of it and it makes sense, even if it wasn't communicated too clearly. I don't think I have the mouse dexterity to constantly keep reassigning people though.
I hope I didn't come off as too harsh. I full well know the reality and limitations of a game jam, which are even more harsh when you're a solo developer (at least Ludum Dare has the 48 hour compo for solo entries as well as the 72 hour jam for any entries).
