Is anyone here in the beta?

I am

Chea dawg.

I think overall Atmosphir is pretty good.  There are definitely a lot of things that need work, but I have confidence that it'll be pulled off well once it's officially released.

It's pretty good so far. The camera definitely needs work though.

I enjoy making levels in it. I did not know that the updates for it would bring in new items to use.

is this game better than little big planet from a purely level creation functionality standpoint?

LittleBigPlanet is amazing, so no, most likely not...
When did the beta come out, anyways? How can I get in it? and when does the full version come out?

It's out now, free for anyone to play:
