You know I actually had a go at making a game like this myself a few months ago, nice to see a more complete version! Okay so things that I felt could have been improved: The missiles just seem really small to me which made them really difficult to see. Also the grab to move mechanic made me quite ill so I couldn't use it. Sorry :)
Things that were good: This is fun, I love the extendo thing for the controllers, aiming was nice and easy.
I think the basic idea of missile command in vr is really good. I just wonder if it really needs adapting a bit (a different setting that allows for a more VR friendly scale or something).
Thanks for making this!
