Great game so far. My only complaint is that I full screened it and there's a lot of wasted space on the screen (1920 x 1080). The font for the story is pretty small and hard to read. Would like to be able to make it bigger.
Better text/UI scaling is definitely on the list for next version. Fwiw, there are two full screen buttons on top of each other - the blue one added by Unity which actually full screens, and the transparent one added by Itch which does the effect you described. I'm still trying to figure out how to stop them overlapping.
Glad you enjoyed it though.
