Quite a fun little game. It's got a spooky ghoul and an impact font meme - what else could I possibly want? I could imagine a lot of ways this could be developed further. There's a battle going on in the background, maybe some of the soldiers who show up aren't quite dead, or maybe there's stray projectiles for you to worry about. But still, what you have here was fun.

Interestingly, I didn't get the bug the other commenters mentioned, running the game in Firefox on Linux. Might be platform-specific or have something else weird going on.

The game was fun to play and the art and audio were really goood. Also the CRT effect gave it an nice flair and game feel. The speedboster pickup also added some variation. It only needs to spawn more often because my last round was impossible to beat (76 highscore). You should also experiment with maybe giving the obstecals an new random location next time.

Also the meme explaning the gameplay was 10/10. 

Like 8BitSquid said, there was a little bug, that your game didn't strech the whole screen. Next time do a little bit of playtesting with the online version. You still had a little bit of time :)
