Tile wrapping
Tile wrapping is an important part of our game. When tiles slide off on one side, they come back on the other.
This was done using a custom animation graph with a fading material, and can be seen on the gif on the right.
Tile highlighting
Whenever the player touches a tile to select it, all the tiles except the tiles in this row and column are darkened. This is to tell the player which row/column they are actually going to move.
Whenever the player then drags in a specific direction, all the tiles in the other direction are also darkened. This can also be seen on the gif on the right.
