Spectro Destroyer is a Puzzle-Platformer with a retro 8-bit look which you can make your own levels for.

You are in an alien base and you have to pass through all the rooms. To do this you need to kill all the enemies in each room. Each enemy has a colour and can be destroyed only with a Laser-Bullet of the same colour. So you will have to shoot on the coloured mirrors in the room to transform the colour of your laser from white to whatever other colour you need.
