As reported by TorrentFreak (thanks, VGC), the Heaven Studio GitHub repository has been removed following Nintendo's request, which cites copyright on the assets included with the software.
The makers of the tool shared on Twitter that, despite receiving bogus takedown complaints from people purporting to be Nintendo, this latest one appears to be the real deal.
Nintendo's legal eagles have been active recently issuing takedowns against musicians and sheet music. The details around that are a little greyer, although with Heaven Studio making use of the game's original assets — both art and sound effects — it seemed like only a matter of time before Nintendo would deploy the ninjas.
The Heaven Studio GitHub page now displays only the takedown notice:
For their part, the makers of Heaven Studio insist that this isn't the end, saying that, "Heaven Studio isn't dead, or going to die, but it's going to be quiet for a bit. We need to make some major changes, and those changes are going to take time."
Let us know below if you ever used Heaven Studio or enjoyed any of the videos. Do you think this could be a sign of something official in the works (be still our bea-bea-beating hearts!), or is Nintendo just protecting its IP in the usual way with a random-looking strike?
