Strong entry. I don't want to say too much and take away from others' first impressions, but I think I can safely say at a minimum that the palette change is well done.
I was a bit confused at first by the cookie pickup mechanic (I can kept trying to just click to pick things up, rather than drag) but figured it out eventually. I also accidentally cued a scene transition by pressing E instead of space to progress the text (luckily pressing space a bunch of times (and maybe e again)) eventually got things sorted out. These feel like minor issues in the end though, the mood comes through and the length feels right. It works well as a little browser-playable vignette. Nicely done.
