Really like what you did here. The varied environments really sell this, being a mix between relaxing, creepy, liminal and outright nonsensical which kept me playing through to the end.
There are a couple things to prod at - such as the transitions between dreams, which kind of feel abrupt. This kind of broke my immersion at points, but even just a fade-to-black a la Yume Nikki would help.
Overall, very solid experience!
(P.S. - found the cat!)
