Ok, for a start, it's not bad. But it's not captivating. The title screen comes out like all pixelated and hard to see. You made your controls decent enough with the arrow, but then made your fire button the ctrl key. For a keyboard that has dozens of keys, why not use the space bar or something else.
Graphicwise, it was alright but it needs a great deal of tweaking. Make a few changes, I'd like to know how many lives left I have while playing too. Good luck on your game making :)
