Very nice, the game looks beautiful and the puzzles were fun! Reminds me of Myst quite a bit and definitely succeeds at creating that kind of mysterious environment where you have to explore every little thing around you to solve the puzzles.
I really enjoyed the particle animations when solving some of the locks as well as just looking around at the different pieces of decoration in the room. Fun ending too, haha!
I did occasionally have a bit of trouble figuring out which controls I should be using - clicking the mouse and using WASDQE on the keyboard sometimes seemed at odds with one another. Maybe I should have just stuck with one or the other, but it might have also been helpful just to have an option at the start for a preferred control scheme and disable the others. You still provided control remapping options though, so it’s a pretty small complaint.
Overall very nice work, I thoroughly enjoyed it and would definitely love to play a full-blown version of this game!
