I more or less enjoyed this.
This game was basically fun and kept me entertained for a few minutes. I only have a couple of minor tips which could improve your next update of this. Firstly, you need to tweak the area on the scarab beam a bit because it hits you no matter where you are and an enemy attack you can't avoid is terribly frustrating. second, you should add mouse over medal descriptions on the post-game carnage screen that tell briefly how the medal is earned. Those are the only ways I could see this being closer to perfect.
