I just see, thanks. I will take a better look at yours later, but at least I have tested it even Math Tower 1, and from what I have seen, it's more fun for children to learn mathematics by playing than doing homework and exams at school.
Please can you put the review on my game page? https://ticosgames.itch.io/mathtower2 , this week I will review your other games because in this place (Amazon) the internet is not good, tomorrow I will travel to civilization.
