Hello everyone!
We're excited to bring our first interactive story to steam, The Artifacts.
A Linux and Mac version will be coming, but not for a couple of months.
We will also follow up with two more interactive storybooks, Hilda Bewildered and Midnight Feast, so keep an eye out for them in a few months.
It takes a fair bit of effort to convert these to PC (as they were originally written in Objective C, and have to be recoded in C++), and it's a page by page labour of love. We will have all resolutions supported, with optional fixed side panels on widescreen resolutions. I've tested up to 4k resolution (3840x2160) and it works quite well.
Hope you enjoy The Artifacts, and let us know if you have any questions/concerns.
