best of the jam. 

Cool premise. I like the art a lot. The biggest problem I think was already mentioned and it's that I brought the astronaut outside the screen and couldn't get hit by an alien. The scariest part is at the beginning when there's no time to figure out what you're doing and then one hit and you're dead., and I  couldn't find a restart button so I had to refresh the page everytime. The true challenge is seeing if you can start the music AND dodge the alien all before the first one hits you. Good job!

Nice idea, but the fact that you can walk off screen means you can never die which takes away the challenge. Good effort & worth expanding on. 

Really nice art! It was a little confusing at first, though, since the astronaut looks like he's trying to catch the aliens. I wish I could control the astronaut with the keyboard, and it's possible to just walk off screen, but it's definitely a good start.
