Sugestion: Add the possibility for stage 4 (or add a new stage) to use real words that contain the selected kana

[hikigaya-haru]

Let me preface with giving you huge props for stage 4, I've never seen anything like it in other apps/websites and it is a great way to learn kana, by seeing them together instead of in a vacuum.

However, one thing that immediately sprung to my mind is that it would be interesting to use real words in stage 4, or add a possible stage 5 (possibly optional?), which might be interesting to create some immersion right off the bat. Of course, not all words are prone to such usage, so something like words with only 2-4 kana and of common usage is what I thought of (like りんご, あお, くるま, etc)

What do you think? Would it be interesting, or do you think it would detract from remembering the kana by adding an accessory item that people might focus on?
