This is fun, weird, bizarre, surreal, and creepy. There's no clear order to any of these events and it makes you wonder what happened in Dust's life, or indeed their whole world. The viewer is left filling in the gaps on their own.
EDIT: OH THERE'S SECRETS. That was so sweet.
The note to Linux users is very sweet, although I do have some good news there: using the Itch.io app and installing the Windows version, it will very transparently Just Run with Wine without any sort of issue. If I didn't see that Windows icon and name in the zip, I might as well not have known it wasn't available natively. :)
Edit 2: this was made in AGS? There's a cross-platform version of that on Github! I think you should be able to release Linux and MacOS native versions for this!
