Really polished and addicting gameplay! I didn't know I could fuse diagonally for a while so I was getting kinda of frustrated and ended up clicking like a madman and then noticing "Oh! I can fuse diagonally" maybe it would help to add some kind of indicator to show which tiles you can fuse into. As well as a title screen that shows how to play the game so that you don't have to read the instructions within the gamepage. Very nicely done! Excellent submission!
