I don't know if this applies to anyone else but for me, the game didn't load unless I went full screen, and when I went fullscreen half the game as chopped off.
Once when playing I got the impression I was supposed to be separating things into buckets, but I had no idea which bucket was meant for which object. Perhaps you assumed knowledge of the colours of the bins, or perhaps there was more info on the right hand side of the screen (which was cut off). Either way, I had no idea how to even win.
If I were making this game I would make sure it works on itch.io (I'm assuming it works on your computer), and I would make it clearer how to play/win.
