Hey, this is great! Scratches my flight-simulator itch for sure. I wish I could use my mouse for pitch and roll and that there were more than one mission. The plane controls feel pretty good, I like the HUD, target selection is good. Thanks for making it!
Had trouble with the terrain library requiring a more recent C++ runtime version than I had installed, but I was able to fix it by replacing the terrain library with a latest binary from the author's repository. (Otherwise the game would have no terrain.)
