Great stuff!
Small UX thing: Make it so you can just click a word to fill in the next empty spot, instead of having to drag, similar to when building sentences in Duolingo. Especially when not on a touchscreen, having to drag is pretty painful and reduces accessibility.
You didn’t even read the most basic settings that clearly say “click and drag interface” or something similar. But I still agree, tapping/clicking should work in sequential order eventually (it’s not as easy to implement).
Re, looping; there are controls to turn it off. You aren’t paying attention one bit. If you’re going to say things, at least be diligent in the things you are going to address.
You don't need to be so combative in this feedback thread for someone's language learning app.
Aaa, you saved me, thought it's broken, but you have to drag this thing!
ps. video shouldn't loop as default, it's annoying.
