Great game! ... Does it ever end though?
I got all the weapons, I wonder if there's anywhere to continue from here (besides zOMGies 2 which I found even harder).
The game is sorely missing a pause button, and for me it was quite tough, to the level that I finished levels only by being lucky until I got the last 3 weapons. I think the rocket launcher doesn't blow up barrels & such within its blast radius but it should, it's anyway slow and not such a great weapon...
Still, it was too enjoyable for me to give it less than a 9, deserves a 10 except for the minor issues above.
