The library tower doens't actually rotate- you always view the same static image if you clime the tower and look out the window. This shortcut appears a few times in the game. I can notice some strange lines converging the sky and on the ground in certain areas- namely near the planetarium and in the sky of the Channelwood age. These could easly be addressed, and should be because Myst is all about noticing visual details. I'm so pleased Rime was added, and that there is a setting to revert character graphics to the old-school video style from the original. Nice touch! Live action Atrus is way better than awkward CGI Atrus!
It's still the best city sim out there!
