Awesome little game. Just for anyone wondering about portrait mode, it works perfect in my project. The only different is the amount of upcoming terrain that you can see coming up. Plenty of reaction time using portrait mode though. The one thing to remember is that gravity is working on the chopper... in other words, the chopper will start to fall unless you use your controls too keep the nose up when you want it to riser. At first, I thought the finger controls made it go up and down... but then I figured out down is automatic and you are just controlling the up part... like a real helicopter! Awesome work MrDavid... such a cheap price for such a great game!
