I like the background music, it sounds like Thai or some sort of SEA - please don't hate me if I guess it wrong ;)) The visual is great, and the idea is quite well thought! Some games focus too much work on the calculation, which then also transfer that onto the player, and made me felt as if I gotta take another after school Math lecture lol. But your game implemented this in a very simple yet challenging way, and I love it! Hope you guys do well on other games too!
