I've published my first game on Kongreagate, its called Alien Attack, you can try it out here:

I want to give a big thank you to the content providers on OpenGameArt for the pixel art, Music and sound effects that really helped me in producing my first game, including:

Skorpio for the alien ships, Fireball explosion by cemkalyoncu, Stephen Challener (Redshrike) for the alien monster artwork

UI Buttons: "www.kenney.nl", Explosion sound effect by Stephen Cameron, Stepping up! victory music by Macro, Game music "Heatstroke" by Jesús Lastra

I've created an in game credits page too.

I now plan on producing some of my own art (cut scenes) to the game to add some background story to the game, and promote my artwork. 

Thanks again.
