Dude, watching my 10-year old dip dive duck and dodge around my living room playing this was so awesome and gratifying! My first 3D shooter was Wolfenstein 3D back in the day so seeing him get started in VR on such a similar game...why it warms my heart! Thank you for this!
As for the game, wow this is ridiculously entertaining for a single level! My son actually beat me to winning it first! He was like "aww that's it?" and I had to explain this guy on the other side of the world was doing this in his spare time. He was like "oh wow, well this is awesome! I can't wait for more!"
Only real feedback that hasn't been mentioned is I'd like to see collisions on the ceiling too, It's very minor but would be cool. Maybe if you add some annoying bats to come peck at you you can fix it at that time? Hah that would be freaky, you're facing a room of soldiers and some bats come down from the ceiling to harass you! Anyway, there's my thoughts.
Take care of yourself over there! Looking forward to the next alpha 0.0.3! P.S. it would be nice if maybe you add a bit more health to yourself.
