[2018] Need a little assistance getting started...

Played this at Pax East after hearing about it on a Panel and fell in love with it. Having trouble tinkering around though - I guess I'm a little slow but I wasn't aware an external controller is required. Any ETA on keyboard controls becoming available? What controllers work besides steam controller? (Not sure which one was used at Pax East). Thanks!

Also please note that mouse and keyboard support is only available for online multiplayer. You can access the online multiplayer steam branch by following the instructions in our discord: https://discord.gg/vmxrVKH
