This minor release fixes bugs and implements suggestions that were reported by Zirquitz's players, mainly the following:

• The tutorial no longer applies weird video settings, should play nicely now on multi-monitor setups
  
• There is now a BACK button (also ESC key) on the challenge selection page to go back to the title screen
  
• Though some of the nodes are derived by "Control" (not 2DNode) and therefore do not resize with the game window, they are now much friendlier to hi-res (2K and 4K) setups
  
• Some fine tuning to the challenge difficulties has been applied, to make challenges slightly more approachable
