I really like the wallpaper and carpet designs and just how cosy the environment looks! The blobs/collectors are also very cute.
I think there might be a bug with the color extractor in the beginning? It seemed to stop working sometimes, as in, the timer stops progressing. At first I thought it was because of an upgrade, but after reloading the page, it got stuck after extracting one dye regardless of whether I upgraded it or not.
It might be nice to have a way to get back to the main menu within the game, so you can start again without having to close everything.
