Yes, I've actually used that app before. I liked it very much, but ever since I upgraded to an Android phone, I've missed that app. As of right now, I don't think I am copying that app (other than tilting the phone to control the steering, but of course, that is more of a general concept that exists in every mobile racing game). The layout is similar probably because I remember the MungoGamer app. I liked the control scheme. However, I will be implementing customizable control layout in the near future. For example, right now, I have the throttle mapped to to gear up and + mapped to gear down. I am using a "ghetto setup" that has a keyboard on the floor acting as pedals for gas and brake

(if you arer curious, space bar is brake and down arrow key is gas; I pried off the up, left, and right keys to prevent unintention changes to brake balance and etc).
Also, since many laptops and even desktops nowadays have bluetooth, I will create bluetooth communication ASAP, which will allow users to play racing games on the go without wifi networks around.
