I will be thinking about this game every time I use blender now. Very creative take on the theme! The pacing was really good, introducing the concepts 1 at a time. I also like how much potential there is for combinations and puzzles, you could definitely progress this into a full steam game, perhaps with some more polished visuals. Maybe even lean into the blender theme.
My only critique would be that at the current size of the game, it is actually bigger than my browser and the unity window prevents you from scrolling. So once the game had loaded I was unable to view the description anymore.
