Wow, really impressive stuff on display here! Loved the game: the dioramas were very pretty and fun to investigate, scavenging around for clues to solve the various puzzles. In particular the controls felt great, especially for spinning the diorama around and doing various click, hold and drag actions for opening chests, flipping books, spinning wheels and so on: that incremental process of slowly opening something or whatnot felt so tactile and satisfying! Everything was just so fluid, smooth and had a professional air to its presentation: solid work all-around!
That being said, I did have a few issues to point out:
One was that I would occasionally click somewhere on the screen, and then the camera would suddenly spin the stage around to focus on something that was obscured from my sight. It was very confusing: basically even though an obstacle was in the way and blocking sight of the interactable, the game treated it as if the obstacle didn't exist and therefore didn't block my raycast of interaction.
Two was that I found the game very inconsistent with what it would want me to just click and what it would want me to click, hold and drag. Most of the time it was fine: click to pick up an item but drag to open a door or a book or what-not. But, there would be times where I would go to, for example, open the lid of a chest, expecting to click, hold and drag the lid open, but this time, for some reason, the game just wanted me to click once and the lid automatically pops open of its own accord. C'mon, the drag actions are the best part of the game and it didn't let me take part for some reason, haha! Just made it quite confusing and annoying to have a double-check what it wants constantly.
Three is a bit of a minor and silly issue: for some reason, I wanted the ability to, say, when flipping the page of a book or anything other drag action, to be able to go back and forth. I don't know why exactly but...I don't mind that once I flip the page completely that I can't flip it back, that's fine, but when I'm in the middle of the action I wanted that ability to go back and forth for some reason: it just felt unsatisfying that I couldn't play around, I guess.
Hoping maybe this feedback can help with the full release of the game, but even without it, I think you got something nice here already, so best of luck with your development and release!
