Thx for your fast reply.
Unfortunately, I really keep away from Steam! I dont even have an account. But not all is lost: i'll play it on android.(If/when you can make a non Steam build in the future, I'll buy it again for PC)
Unfortunately we don't support Android version at this time and don't make new builds for it. So that's why it's free. But we plan back to this platform in future.
We've uploaded DRM-Free version to itch.ioHave fun! :)
