Hi,

I have just updated the build on the itch-page. Node highlights are now computed in screen space and the final piece of the soundtrack has been added in.
The current plan is to release the game on itch.io next week, May 10th, to make it easier to distribute keys. When the game gets greenlight, I'll try to add Workshop support, but other than that, I think the game does not lack anything crucial anymore.

Here are the changes:
Game:

• node overlays are now computed in screen space (so they do not rotate with pattern nodes)
  
• pattern nodes' rotations are now synced up
  
• moved some levels from Borders to Spinners, added a new level to Borders
  
• he top-right menu buttons are now mip-mapped
  
• the level history menu now works again
  
• added the third piece of the soundtrack
  Editor:
  
• exiting the editor now aborts any solvability checking that may be in progress
  
• the editor now won't let you place more nodes/edges than the game view itself supports (120 and 500, respectively)
  
• the randomize/transform windows are now mutually exclusive
  
• the level editor now warns you should you discard unsaved changes
  
• you can now rebind most of the keys for the editor in the launcher
