As I mentioned before, the UI could be a bit more intuitive. It was a bit too hard to do things with a purpose and a bit to easy to do thing on accident (like quit the game or close the app). A bit more focus on making things work in such a way that players don't even need instructions goes a long way.
Graphics are good, especially for a first 3D game. I like the theme interpretation.
I'm not sure why there was problems with loading on Windows. I installed in on my Steam Deck running Bazzite and it runs just fine.
