Preatty neat game. Love the visuals and that no fusion fuses doubles and the music is nice too. However it would be nice to have the elements that were fused with certain other elements could be marked. Cause ngl I've lost track of which element I've already fused ir didn't fuse with the other element. So now I'm just relying on the hints to do the work for me lol
