I WIN, it took me 2 tries as the first time I got cocky and didn't get rid of all the thugs and focused too much on the boss (had to relaunch the game, after pressing Restart the enemies didn't leave a piece of waste when they died).
The game looks cool, it's punchy (I like the sound effects), it's fun to navigate through the bullets and more and more waste and the boss fight is cool, from the introduction to it with the waste gathering in the middle of the screen to the difficulty increasing as enemies start to join it.
Cool game!
