A new update is available now! 

New features:

• Title screen has changed. It now shows the version of the game and an 'OPTIONS' box;
• The 'OPTIONS' shows the controls of the game and it allows to play the game in windowed mode;
• You can now use 'Enter' to confirm, 'Backspace' to go back and 'Space' to jump;

Bug fixes:

• Fixed bug where the wrong font would load;
• Fixed bug where if you pressed 'Z' while loading a level, it would take you back to the title screen;

That's it for now! Please feel free to tell in the comments any bugs you found!
