Couple of quick points..
It flies great, really good feel. Its performance on my 2019 MacBook Pro is shaky at best. I put it on the lowest settings with metal and got 13fps. Without metal I was able to get it up to 22ish fps.
The hypoxia simulation is pretty cool, I had no idea why the screen was going dark but it eventually it made sense :). Unfortunately when I hit the oxygen switch (down by the flap switch) nothing happens. I also clicked the button to refill the oxygen tank in the maintenance menu but no luck. I would love some help here.
