You made airplane physics too? Cool! How long did it take you? It took me 6 hours and 3 attempts to get something I actually likes. I love the game, but it is so stutterey and if you go too fast, you just stop in midair, which ruined many of my runs and made diving useless. I managed to get 575 after a lucky placement of obstacles. If you have a downloadable version, I would love to play that!
