This game is so interesting but can't understand when game over.

This game is very unique. This game is little hard for me.

The idea is novel and interesting.

It was an interesting game! But the needle was hard to see.

I thought that it was an interesting idea that an abacus expressed a calculating formula.

 I think that the picture of the torii is good.

I think it's a very wonderful game. I felt that it was a game that was good at both education and play. This is interesting.

I can't see the needles.

And I can't read the abacus(Japanese sorobann).

This is a nice game. It was very interesting.

I think it's better to write the abacus calculation method in a place where you can read it immediately.

It was very interesting that the theme was abacus, which is very familiar in Japan.

An interesting idea, and the execution is not bad! Was surprised to learn that not only does Japan have a distinct kind of abacus, it’s apparently still being taught in schools today. The graphics for different numbers on the soroban are kinda hard to tell apart, and could be improved, but it’s possible to get used to it.
