Since I'm still stuck trying to solve this HUD problem I've rolled back the UI to the previous system which worked. Now there's no HUD in the Oculus, but I wager that's fine for now - learn to play in regular mode and then try it out on the Oculus if you're so equipped.
I've only updated the Windows version, because the Mac users who reported in said the HUD was working for them.
So, if you're a Windows-using Alpha backer and want to be actually able to play the thing as intended, go get it! Same Energy Hook place, same Energy Hook channel.
