The frog animation is hilarious! I enjoyed the game.
One area I was a bit unsure of was when to expect the game to end. I did reach the end screen after a few potions, but it wasn't explicitly obvious how much time or how many moves I had left (unless it should have been obvious and I just missed it). Just a quick text stating "go until no moves are possible" would fix that.
Nice match-three and great Halloweenie theme! Would love to see the additions discussed below.
