Neon contains four games in which you have to collect neon tubes. Each game has an enemy that shoots at you or you have to avoid. The games can be played in any order.
One game is a Pac-man clone in which you have to collect the tubes in a maze and avoid the roaming smiley face.
Another has you collecting Five tubes that randomly appear on the screen. Four enemies patrol the screen edges and take pot shots at you.
A third has you collecting 13 tubes in a circle and avoiding the enemy gaurds.
In the last game, Collect as many tubes as you can before killing the enemies chasing you.
