How do I use it?

If you need an explanation of how this works, I've made a video here: I made a computer out of crabs

There are also some simple circuit designs here: What are phase crabs?

And for some more complex circuits (including phase crabs): Finding bugs in my own game (Crabs)

Please download the regular version!

The WebGL version of this game is a preview and will not be able to handle complicated builds, so if you like the game, please download the Windows version. If you have a different OS, please let me know and I will port it for you.

I hope you enjoy :)
