|Nekodancer is dead|
They are trying all their best to solve the problem so.. It's not said how much time it will take but for sure the videos won't work for another few months. Just be patient..
I wish they just killed the game off, to be honest. Don't get me wrong, it's my favorite game from Atelier, but it feels like an insult to know that they haven't just not updated the game for years; once it got demolished by YT getting rid of the Flash player, there's no courtesy to even turn around and say "Oh, looks like the game died, maybe it'd be nice to give it the funeral it deserves."
They might be saying they're looking for a way to fix this, but I just can't see it happening with Flash at all. Even if it could be done by ex. changing the engine from Flash to HTML5 (and I doubt that's the case, since I barely know anything about programming), considering the [lack of] popularity, this will be done at a pace where you may very well say "This is never going to happen."
Do you still have any hope in Atelier801 doing anything about the broken games? Not only Nekodancer, but Fortoresse (Utterly Broken) and Bouboum (Hacker Fiesta). They are not doing anything, and you need to understand this.
The only reason they might be working on the video issue is because of TFM. If they are gonna implement it on Nekodancer? Dunno. They already used this shitty UI in all of their games, might aswell just put TFM fixes on all other games to make it look like they're fixing it!
