Well this was a fun take. Have not seen it anywhere else. Took me a minute to understand but the feeling of landing a combo on an enemy and popping them is great. Good job there. Not sure if I missed it but I was hoping for like a final score when the mobs finally got me. Also I was never sure how much health they had so I usually tried 5 of a kind to ensure death. Maybe some color changing as they lose health or something.
Overall good job there. I had fun and thats always good.
