In the 3D reaction game Gate Rusher, your marble is hurtling down a curved track interspersed with barriers. There's an open gate placed along each barrier, and you have to swerve left or right to pass through it and avoid a collision. The barriers are transparent, so you can see some way ahead of you. Make sure you pass neatly through the gates or you'll lose the game. If you hit a wall the first time, you're given a one-time option to continue playing. You'll restart exactly where you left off, so react quickly to avoid making the same mistake!
