It looks really nice. Played like a dream.
I enjoy the time travelling and the quests.
I will list the two main defaults I encounterd :
1) The quests location : I dislike having to talk to 12 NPCs to look for an object. Here you will either see right away or look for a while. Obviously you can activate the localization and instantly know what to do but it is less fun.
2) the "running" update. The game isn't hard even on hard so why make me wait 15 hours to be able to run into ennemies without losing the speed up spell?
It doesn't make it harder but more tedious yes.
