Magic Light is a puzzle game and an original creation exclusive to Casio Graph 90+E (and other Casio fxCG10/20/50 models) and TI nSpire CX (II), taking full advantage of 16-bit RGB565 color screens.
After a stylish animated start menu, let's get to the heart of the game.
You must explore the different rooms of a dungeon, searching for fragments of light stolen from the Villagers by the Dark Wizard and his four daughter witches, in order to restore color and joy to the Village. To do that, you need to reach the wizard's castle fortress, where he hid his loot.
But doors are locked and can only open if you solve each room's light puzzle. Around each room there are doors and sensors reacting to specific colors. Each door is connected to 1 to 3 sensors and only opens when all of them are lit simultaneously with the correct colors.

In each room, you can move several elements with the arrow keys after selecting them with [F1] to [F6], matching the bottom-screen menu:

the main character who must leave the room ([F1])

a crystal ball emitting white light, initially in the center ([F2])

light-filtering blocks that only let certain colors pass: red, green, blue, and black blocks ([F3 to F6])

Of course, the castle is swarming with monsters, and the Wizard and the witches will do everything they can to stop you from reclaiming their loot and bringing it back to the village. You will need caution, dexterity, and clever thinking to make it through. The physics engine developed for the game projects accurate light beam shapes onto walls and obstacles, and also supports:

fixed blocks in some levels that can block light paths

combinations of light-filtering blocks to create new colors through additive synthesis

You will need to think carefully to place everything correctly, while monsters constantly get in your way.
