Some things:
The swords youre throwing are facing backwards.
The car, grass, and like evrything, didn't you make. Thats okay! Your're not a Game Designer. You are more of a programer. Thats cool... BUT, the programing sux too :P
1/5
Even though I know this was uploaded 2009, I will comment:
Great first game!
A bit fail with the down key. It stops the spaceship so that makes the game easy. You never lose control. Fun though!
Have a nice day!
