I don't think I would ever have expected someone to merge the "Crafting" (Doodle god, Little alchemy, ...infinite craft....?) genre with the clicker game, but this was a pleasant little surprise. I especially love using emoji as a visual style. Like others have said, when the characters are zooming down the track, it's a little hard to keep up. One thing I'd probably add is an in-game recipe list? Obviously only show what I've crafted before, I just had a hard time remembering what recipe I used to craft what item.
Clever game.
