Tube SE

You're driving some kind of ship and must make your way inside a tube as fast as you can. There is indeed a horde of zombies after you and you have to escape them. You never see them in the game, but belive me, they are right behind you!

Your goal is to reach the end of each track as quickly as possible. This isn't as simple as just going forward, though. There will be obstacles to slow down or stop your ship. There are also aids to temporarily increase your ship's speed or help you avoid obstacles. Some obstacles will destroy your ship and cause you to restart slightly behind the location where your ship was destroyed. Your ship can be destroyed an unlimited number of times.

Tracks 10 to 18 are locked. You can unlock them by completing a "challenge" track. A "challenge" track has its default time much lower than 99 minutes. When you complete a "challenge" track, you receive an unlock code. You can enter the unlock code in the main screen by pressing up or down, then input the code using the numeric keypad.
