Introduction[]
Good Eye is an Infinite Mode achievement in Run 3. This achievement is found in IM level 303.
Gameplay[]
Note that in each platform, all the conveyors in the "middle" of the platform are fast, whereas only some of the platforms in the left and right are fast.
One of the characters you can use for this level is the Pastafarian, which allows you to walk on the light bridge (but make sure to touch one fast conveyor tile). Another way is the Student. With her slow speed, you can see easily where a slow one is and where a fast one is. A third option is the Bunny. It is mostly luck-based with the Bunny, but you can minimize your chances of hitting a slow conveyor tile by making large jumps over the level.
Trivia[]
The phrase "have a good eye" means "someone who is good at seeing small and important things that other people might not notice", which reflects on how hard it is to see the different types of conveyors in the level.
