Now Archtower finally has an official Steam Demo!

As it goes demo to Steam it has to become the same demo on itch.io
But you can still play the bigger version, for that go to my discord and request keys for alpha testing.
But keep in mind that alpha keys will be deactivated with an Early Access release.
