Fantastic, thanks for letting us experience the development. I also took a sneaky look in VR using vorpx. It's great. And I played arcade ambience sounds in the background. Can't wait for further updates.
Looking great so far, very impressed. The endgame could be something similar to 'new retro arcade neon' which uses fake attract screens. And runs in 2d or VR. Take your time.... Like you say, a bit at a time.
Wow, this is great. This would be awesome in VR. I see you are using Unity which I think has VR support built in!. I already play in full size in VR, but a flat VR desktop window. This is the next evolution.
