Hi thanks for playing, glad you enjoyed the demo. Right now our primary focus is PC, the Steam store page is awaiting approval and the demo will be available there too.
As for the future, based on success we certainly aim to bring the game to the Switch and more however its still uncertain right now.
There's also more info on our website and a mailing list if you would like to follow more closely.
