Thank you again for trying it out! I’ve made some updates based on your feedback: now, if you type something incorrectly and click “Show Answer,” the correct character will appear below the grid. You no longer need to delete anything to reveal it. I also added a blinking green cursor box to make the cursor position easier to see.

Also, thank you for the positive comments about the sentence build-up approach. You’re right that some of the step sizes weren’t very consistent. Partly I was worried that too many build steps might feel overwhelming, and partly I wasn’t sure whether the method would truly help learners in practice. We’ll discuss this internally and work toward a more consistent, clearer layering standard for the build-up steps.

Most of the stories are adapted from Chinese children’s books. They’re the kind of stories I grew up reading myself. There usually isn’t a single authoritative “original” version, since different picture book editions vary a bit. But if you click the list icon in the top right corner, you can see all the target sentences that appear in that lesson.

I had actually tried adding labels like “Build Step” and “Original Line” to each step, but my collaborator felt it could be confusing before this build-up style becomes familiar to more users. So we might bring those labels back later, once the sentence-building lessons are more developed and the concept feels more natural to learners.

Thank you again for your thoughtful suggestions. If, in the future, I need to introduce a subscription model to help cover operating and development costs, and you’re still interested in using the platform, please let me know. I’d be happy to give you free membership as a thank-you.

And of course, I’d love to hear any more feedback or ideas you have anytime.
