I had fun playing your game. The controls were simple and as soon as I learned what I was supposed to do I was smooth sailing for a long time. So there are three speeds and your vehicle must be moving at the coinciding one when passing through the corresponding speed signs. When you see a ghost, you pull the lever. It sounds like a simple premise but I feel as though it could be elaborated upon. Have you ever seen the show called Star Wars: Star Tours? In it, the navigator of the vessel takes you on a wild ride with many twists and turns and things going wrong during the trip. Perhaps you could expand upon the story and have the navigator mess up from time to time to make it more scary. You could have scary encounters like zombies passing by here and there. Cool, fun, neat, little game!
