HAHA punishing people who pollute the nature is great >:] Jokes aside this was a fun experience i love how there are many options you can choose to punish people my favorite is the classic thunder :D
I noticed that some props pixels per unit was diffrent if you make all of your sprites pixel size the same that would be better. Also you can disable compression and smoothing for low res sprites that way they wont be smooth and blurry.
Other than that it was fun playing nice job :D
