For the past 8 months, I have been working on localizing the (almost) full game and also adding some minor stuff.

Changes:

• Game is fully localized, from UI text to menu and others
  
• There are now subtitles in the game
  
• 5 new language options have been introduced (German, Spanish, Portuguese, Russian, French)
  You can find who contributed to these in the Credits
  
• Gotta Sleep has been completely revamped, including his sprites and game mechanics
  
• PlayRobot's sprites have been updated
  
• New item: Somebody's Calculator
  Right click a chalkboard while holding it to instantly answer the question correctly. Unpredictable consequences may arrive upon attempting to answer the impossible question using this item.
  
• After Hours has been buffed (this has also changed the ambient lighting color of Cell Mode)
  
• Dave's speed in Teleportation Madness has been decreased slightly
  
• In Teleportation Madness, Dave now teleports closer to you if you get too far away
  
• Fixed bug with the Sunglasses where if you had an FOV that was different from the default it would be offset
  
• Fixed Algebra Antics bug. Do not try to cheat. Haha
  
• Most audio in the game is preloaded, which should minimize the amount of lag that occurs when any sort of audio playing occurs
  
• In Cell Mode, Crypt and Creep will attempt to avoid Crawl in order to prevent them from getting stuck on each other
  
• Crawl now periodically teleports to your nearest location
  

I believe that's everything. I've changed a lot so I've likely missed some stuff but that should give you the scope of what to expect. Dave says: have fun!
