A 2D, grid-based, synchronous, spatial navigation puzzle game.

Navigate a grid to place every token on a goal. The tokens move in sync with each other, so you have to take each one into consideration with what direction they will move.

There are three game modes – Four tokens (TETRA), Three tokens (TRI), and Two tokens (DI), that’s how I came up with the name Tetridi.

There are 60 levels, 20 from each mode. They are all unlocked so if you get stuck on one you can skip it until you want to come back later to improve your score.

You can change the colors at any time by pressing the 1 through 0 keys, and you can change the sprite design at any time between three different looks by cycling through them with the – and = keys.
