Beautiful art, I love every bit of animation in here, love the hard aliased lines and appealing characters.
The tone is successfully surreal, and able to be both tender, and quite unnerving when it needs to be.
I did find much of the puzzle design to be rather frustrating, leading to a couple of moments where I was very much taken out of the atmosphere of the game, and even almost quit. (Specifically not having any indication that there was an inventory system with usable items, and the invisible maze. The former of which actually made me reset the game because after trying to interact with everything in every room I could reach, I thought I had just softlocked myself somehow)
I think that having something more in place to guide the player and keep things moving would go a long way. That may feel like weakening the gameplay elements, or the surreality of the piece, but your art and atmosphere alone are more than enough to carry a project.
The anticipation of the next piece of art, animation, or narrative is what kept me going through the frustrating parts.
Definitely going to check out your other works, genuinely excited to see you make in the future.
