Fun concept, good job.

I feel like a more grayish color for the brown balls would have looked aesthetically better, and I'm not the biggest fan of the font you used for your UI. But I enjoyed the gameplay, excellent job of keeping it simple and polishing it to make a better game overall.

My comp can't play the web version for some reason. Plz consider adding a windows version. Did not give a rating.

I like the concept, and you make it work rather well. A few things/ideas/nags:
1.) The game didn't fit on my screen. And I have a large screen. This should be fixed.
2.) I would recommend you play around with the gravity. This would make it so the balls didn't float around so much. Might not improve the game, though.
3.) The game is actually really easy once you get the hang of it. Maybe have the difficulty increase over time to some extent?
4.) I'm not sure what the unconventional weapon is. You aren't exactly a weapon in the game, as your description implies. I just don't get it.

Overall, though, well done!

"not my cup of tea". Screen area is to big for my resolution.

Thanks for the feedback folks.

I fixed the size of the web version as well, it's a lot smaller now.
