Thanks for the feedback, I did some fixes/additions to the game:

Fixes:

• A serious bug with the Good Ending was fixed, it's not supposed to say "Thanks for playing" no, it was a coding mistake I did while making the changes for Steam version, I apologize for ruining that moment, if you beat that last level again, you will see the true ending (But update the game).
  
  
• The key mapping bug got fixed too, now arrows works fine on the setup.
  

Additions:

• Added 1920x1080 resolution support.
  

Thanks for your support, and sorry for the inconveniences.
Sincerely, Emmanuel.
