The crystal universe is a new grid-based puzzle game.
The objective of the game is to uncover all the crystals that are hidden in the grid.
Cells in the grid contain either a crystal, a mystery object, or a distance to the nearest crystal.
The metric that is used to calculate distance changes at each level of the game.
The different metrics are Linear, Quadratic, Cubic, Exponential, Logarithm, Logistic, Arctan, and Force.
There are two different types of selection: Cell and Crystal.
Choose Crystal to select a cell you think contains a crystal, and Cell for any other cell.
Points are gained for correctly identifying crystal and non-crystal cells.
Points are lost for misidentifying either crystal or non-crystal cells.
Each level of the game has seven stages. Each new stage has one more crystal in the grid.
The game ends when all the crystals have been correctly uncovered or a crystal is selected in cell mode.
Achievements can be earned by successfully completing a level and obtaining a high enough average score over all stages in a level.
Gold, Silver, and Bronze medals are available to be earned at each level.
Watch out for mystery cells.
Mystery cells include balck holes, worm holes, and entangled cells.
Black holes hide the distance metric from you.
Worm holes come in pairs of cells. One will be next to a crystal and the other will not. If you uncover one side of a worm hole, the other will be revealed. This can help in locating crystals.
Entangled cells are cells that are entangled with each other. One is at a minimum distance to a crystal and the other is at a maximum distance to a crystal. If you reveal one entangled cell, the corresponding entangled cell is automatically revealed.
