I've completed most of the initial area and I've noticed a few issues. Some of them seem to be done on purpose, while others might just be oversights.
I know some of these have been listed under other posts and I tried adding to those when I saw them to make sure they get more attention, but I'm making this list for stuff I'm thinking of.
Free Cam option - Being able to change the angle at the least would be super helpful. I don't know if you want to revamp the tactical view to an unlocked version where you can change angle and height, but there's certain point, especially in indoor environments, where it would make it a lot easier to see stuff if we're not stuck with the default view or overhead.
Cantrips - The main thing I'm thinking of here is that cantrips shouldn't require a rest to use again. I'm not sure why any of them have this requirement since cantrips are supposed to be limited spells that can be used whenever. From the little bit I've gotten to play with it, I noticed in the case of mage hand, there doesn't seem to be a range limit on how far away the hand can get from the caster, so I'm guessing that's why the short rest was put in, but I think the 5e version is perfectly reasonable. Get rid of the short rest requirement, then change it so it can't be further away than the default range. The others like minor illusion might need some additional tweaks like this, but cantrips should not be a consumable resource like spell slots.
Rogue Assassins Assassinate (auto crit when target is surprised.) - I've noticed that as I've been sneaking around and making the initial sneak attacks on unaware creatures, that I'm not getting the automatic critical hits. Technically for game mechanics, they haven't gotten the surprised condition yet, since they're not in combat yet, but it ability should also include unaware targets or out of combat targets. I'm not sure how the engine defines targets who aren't in combat yet, but I can guarantee you that they're surprised when they get shot at.
