Hey, thanks for the feedback everybody. Kill counter has been added, and insta-death has been improved (you no longer should be able to get hurt from your own bombs, and you should be able to collide with several drones without dying).
I'm bummed and somewhat pissed that this game didn't make the top 15. It's a really clever concept (lava-floor was an almost daily occurrence growing up), and better IMHO than a lot of the games that did make it.
