I built an Arabic Number Learning Tool as practice for educational software products, tell me what you think

Hi Indiehackers,

I recently became interested in the space of educational software.

Figuring that at the core of that space is building tools that actually work, I'm building a series of free learning/tutoring/practice tools. My first one is to practice numbers in Egyptian Arabic: https://arabic-numbers.koljapluemer.com/

Please tell me what you think of my approach and the tool!
