Heheh, I usuallly don't check other forums besides Kuribo, but it's good to see you guys like it
We're currently in the process of planning out another trailer, and we have quite a bit of progress on the game, mostly with designs, but we're getting modeling done too.
About the Dolphin thing, we won't support it, just Riivolution, but the aforementioned Mega-Mario who runs Kuribo, along with other projects like Whitehole, a 3D editor, is working on WiiExplorer, which should eventually make it easy to edit most of Nintendo's archives and ISOs as well, making it much more easy to insert new files if you really wanted or needed to use Dolphin.
We have quite a bit to show off, actually, but I'd rather just wait until the trailer to show off most of it, but if you liked Bob-Omb-Battlefield, I think you'll be pleasantly surprised.
And about the gravity comment, we do have stuff like that planned, quite a bit actually, but we also have wacky galaxies and themes, such as time, mirrors, giant fungi, giant chasms, jungles, food, and returning themes, like snowy, poison, the starball, spooky, beach, and the list goes on.
For now, here's some stuff to tide you over.
