The biggest addition to the 2.0 update was one more scene added to the end of the game. In addition to that was the addition of the image gallery, and numerous numerous bug fixes.
2.0 wasn't really a huge update, but after 1.9 I figured it would just be the least confusing to go onto 2.0 instead of like 1.91 or something like that.
It's a bad habit, but I didn't create a devlog for this update because I've been working on a few small fixes and wanted to get those implemented and updated before I did so. In the future I should probably always do a devlog and make smaller bug fixes 2.0.1 but hey, live and learn I guess lol
Thanks for the question!
