Mythical Games Game Idea!

Names isn't my strong point so for suggestion purposes I have called the game Track Controllers!
This is a simple game where everyone spawns on a mine cart in a cave based arena. The floor is covered in railway tracks. The aim is to ride the mine cart and make it to the beacon in the middle. However the tracks are incorrect. While driving you must click the levers next to the tracks that cause the tracks direction to change allowing you to create a path to the middle. In addition if you go certain ways you can find special items such as a flame bow which can be used to shoot the TNT on the caves surfaces to blow up your enemies setting them back to the beginning.

That's the basic rundown of the idea :)
