Really fun concept! I love me a good old boss fight! the 3D bullet patterns were fun to dodge, so were the bombs and the tornadoes. The toon shader works well, and so does the little explode shader when the bombs explode. I will say, and maybe this is unique to the web build, but there's no sound/feed back when picking up the trash, so i cant really tell if im too far away for the F button press to work.
But all in all, good entry!! Congratulations on the finished product!
