For anyone interested I've worked a good bit on the game this weekend and have a rough menu system, sound effects for shooting and explosions, an endgame state (so you can actually lose now!) and enhancements to the "time change" aesthetics. The bulk of the work has been trying to get my head wrapped around Unity's new action-based system for VR as the documentation is tough to get through. I experimented with adding more motion in x and y and possible rotation, but that QUICKLY seems to induce motion sickness. My next big update will be implementing some interaction into the cockpit so you have a functional virtual lever to control the back and forth motion and a virtual "pixelize" button for the pixelation of enemies. Then it will be working on a different weapon system and trying to gamify everything to make it more fun.
