A short factory building game with a single tile type with 4 different possible states/colors.
Made for Mini Jam 183 - Calculations, with the limitation of 4 colors.
All interactions must be discovered or if you want some hints to start:

1. Movers move in a direction until they hit a wall or collide., where they then turn into scanners.
2. When a mover enters a scanner, it turns based on its Color. However each scanner Color also has an effect, either on the mover, the tile directly in front of it or itself
3. The goal is to turn the input of blue movers into an alternating sequence.

Direct Explaination of Mechanics(rot13):

Developer Note:
This didn't really turn out quite how I wanted it to but I didn't want the development time to go to waste entirely so decided to just submit a single screen level that uses all the mechanics. The interpretation of the limitation was that there are only 4 states/colors that movers/scanners can be in each with different effects, as well as being the color palette for the game. 
The palette is Purple, Blue, Grey, Green. (Including shades and excluding black and white. 
I might revisit this concept later if I feel like it.
