This game is just about raming your way to the goal. You use the right/left arrow keys to go forward and reverse. You need to destroy the barriers in order to enter the goal.
When I had the prototype tested, many people wanted the difficulty harder. Also there was a bug where you just needed to be next to the barrier to destroy it. I had made the game harder by increasing the number of bombs as the player progressed through level. I also added rocks as obstacles which I feel were successful because they were not easy to destroy. The reward for getting to the end is being able to get an upgrade of your choice.
