If you want to test your logic skills The Signal State is the right choice. This game is set in a post-apocalyptic future, and your goal is to rebuild an abandoned farm, to repair machines, and be part of the agricultural revolution. Solve complex puzzles inspired by modular synthesizers.

The Signal State uses a simple drag-and-drop system. But don't be fooled by its simplicity. You will have to use your full brain power to manipulate inputs and patch cables in these unique modules. 

Test your abilities and rank up the competing leaderboards. Show everyone your machine whispering skills by completing more than 40 puzzles. The game offers 3 different cable rendering styles, and color palettes, allowing you to customize it to your preference. 

Immerse yourself as you never did before with designs by Papernoise. He also designed modules for Hexinverter, Mutable Instruments, and others.

You will be able to create your own puzzles! This is one of the best features of the game. Max out your creativity in this puzzle designer or try other players' creations via Steam Workshop.

All in all, The Signal State is a brilliant tactile puzzler that transforms the tangle of cables and muddle of modular units into a competing, and challenging game of logic.
