434093 Racetrack/Vector Racing game for Android

The idea is to make the pen-and-paper game Racetrack (also known as Vector Racing and many other names) available as an Android-app/game. Please see "[login to view URL](game)" for a description of the game and its rules. Requested specifications: 1) 2-4 players being able to play on the same phone/system (if you can make it playable between phones over bluetooth or wireless network this may merit a higher price), marked by different geometrical shapes or colors. 2) Controls based on simple press-and-hold on the screen. When you touch-and-hold on the screen, a line which shows where your marker will go (current "speed" + one the extra box/pace in a chosen direction, or no additional pace if released close to the middle), and releasing to make your move. Alternatively simple arrows along the border of the screen, if the first method of control is very complicated to code. 3) Possibility to make your own game-maps based simply by drawing a inner and outer line directly on the screen. Preferably the self-made maps should saved as separate files on the phone/system to make map-sharing available. There is no hurry for this project, but please let me know your time estimation when you leave your bid.
