There is a new prototype version here and a new devlog on Steam! 

Version 0.3 just released and is a huge improvement on 0.2 with:

• A new UI framework
• A new art direction and rendering pipeline
• More blocks
• Two layers of blocks: shape and paints
• Auto-saving worlds!
• Reconfigurable controls
• Cute monsters you can fight (they can't fight back though, digital life is cruel)

Wieldo also has a brand new Steam Page where you can wishlist the game and read a new devlog entry.
