Very satisfying! Just a few little things that I feel would improve gameplay:
- The UI covers the book stacks so I couldn't see all my books at the end
- It doesn't seem I can put books in new stacks when I remove all the books. This affected the upgrade when buying more auto-sort stacks.
- I personally found the ability to scroll around with the mouse a little disorienting. I'd prefer just to use the arrowkeys to move around. Maybe this could be toggleable?
Overall great! Can't wait to see where this goes
