LetterNum - Alphabet & Numbers

Greetings from a young parent!
I decided to make an educational application for children with a minimalistic but bright design so that nothing would distract the child from learning.
It all started with the alphabet and gradually expanded to several categories of teaching children.
There are 10 mini-games in the app:
1. Alphabet for the little ones. Autorepeat with the ability to change the speed of displaying letters.
2. Alphabet for older children. Choose letters yourself from the list.
3. A to Z. Find the letters A to Z in the jumbled list of letters.
4. Write the word. Make up the word shown in the picture from the jumbled letters.
5. Draw a letter. The opportunity to practice writing letters from the list.
6.1 ... 10. Find the numbers from 1 to 10 in the jumbled list.
7.10 ... 1. Find numbers from 10 to 1 in the jumbled list.
8. Choose a picture. Select the picture with the word written below.
9. Memory game. Find two identical pictures from the jumbled list of hidden pictures.
10. Simple arithmetic. Solve simple addition and subtraction problems with picture guides.
Thank you for your choice!
I would be grateful for your feedback and suggestions!
