Your game was fun and easy to pick up and play, but hard to put down ahah!
I really liked your usage of the theme and limitation. The art, music and sounds were clean and not too distracting. The effects when you make a combo felt good and clear to understand as well.
You could add a mini-tutorial message on the top at the beginning of the game so the player understands more easily that they need to make sums of ten. I was trying to match numbers before reading the instructions ahah.
It would also be interesting to see different types of tiles in the future.
Great job and keep it up!
