Just a piece of feedback about that.
Well, in this case, I will commenting as Android User (Using Google Chrome for Android)
I saw the subtitle text were bit awkward since it make the page like moving up and down. Well, this one not really a huge problem, instead something that called for a bit annoying.
For Layout's of website in general, that is good for seen, but something budge me about this. Are the position and layout were looked like this? Somehow, like the placing of the option were bit awkward in someway. Somehow, we could see that view were needed for user to put a bit longer time to understand how to operate. I hope in the future there will be some improvement regard of this point, at last, even the dummies could view as "users friendly".
And last, I hope there will be some captions / subtitles that's mentioned about some action that were done (SFX being subbed). For example like "inhales", "walking sound", "sigh", and ect. But well, not every subtitle must had those in their subtitle. At last, there will be 2 variants of subtitles that viewer could choose, the normal one, or the one with SFX's subtitles.
