Pixxie has just added a bunch of Frogman avatars. You can change your avatar in the Home section of your account.
I've added an RSS news feed for this blog. The RSS button is on the top left of each post. Maybe you need to refresh the site to see it. If there are problems with RSS, just let me know.
P.S.: We've been featured on Kotaku again! Here is the article: http://kotaku.com/yep-cube-world-still-looks-adorable-513099276
