One4 is a 3D puzzle game where you compete against Artificial Intelligence or your Steam mate in a formation of cubes made in glass. Your aim is to fill four cubes with your characters in a row.
There are three game modes:
Basic - a game where you put characters in their respectable places.
Drop - you have gravity, and you drop the character into the set of cubes. After dropping, you need to spin a slice of the cube. Characters fall down as gravity hits like a hammer.
Rotate - similar to drop, but you don't have the gravity.
