Additions:

• The game now supports up to 4 players locally.

  Number of players for local sessions can be adjusted via the options menu (under "remap controls").
  
• The game now displays previews on map selection screen.
  http://steamcommunity.com/sharedfiles/filedetails/?id=757527375
  Preview "thumbnails" are now stored alongside the maps in directories.
  Thumbnails are generated for maps upon saving.
  If you've published a Workshop map, update it with the same file - thumbnail will be packed in automatically.
  

Changes:

• You can now load maps from Workshop in the editor.
  In case you need to edit your own map or want to look at how things work.
  A local copy of the map is made upon saving.
  
• Mouse wheel is now used for scrolling large menus.
  (was previously used to switch "< carousel >" type controls)
  Also menu scrolling in general received a small overhaul.
  
• Player scheme selection was moved into "remap controls" sub-menu
  (to account for there now being more menu items)
  

Fixes:

• Fixed Steam screenshots not working correctly.
  
• Fixed a crash upon picking invalid files for a tileset image in the editor.
  
• Fixed a crash upon entering invalid (negative) map size in the editor.
  
• Fixed fan' wind effect animating faster in multiplayer games.
  

Next up we are going to look into improving lag compensation, getting the game to run at 60FPS (currently runs at 30FPS), and adding more content. Suggestions are welcome!
