In this update, I added a few new things and changed a few other features.
Now the game is fully compatible with any controller (I think Playstation and XBox controllers work out of the box, for others you should use the controller setup app included to use the XBox controller emulator.
Hopefully, the game isn't broken, and I think things are ready for the public presentation at Lisbon Games Week.
Thanks for your support, and please do give me your feedback and opinions. 
Cheers.
