Whew. Finally had some time to test out some more games.
Definitely like the art here. Are you mimicking BlackThornProd's art per chance? Because these arts kinda remind me of his arts (^_^;
The music is ok and definitely fits the game. It's kind of unfortunate though that you did not add some sound effects in the game even though you added a music and in the game description you did say you are a sound designer (did you actually add some SFX but I just missed it? D:)
I guess gameplay wise, even though I have got a feeling that this is meant to be a puzzle game (primarily because of the restart button), this is more of a skill-based game isn't it? The way to go is pretty much always to not collect any garbage and dump the initial garbage -- the only difficulty is from avoiding the garbage littered everywhere and those pesky Pauls (lol). There is absolutely no reason to collect any garbage, and the level design doesn't force the player to collect any necessary garbage or choice of garbage to collect for example. I guess the only necessary thinking is choosing which bin to throw the garbage into sometimes since the bins magically disappear once they're full.
Also... I hope this doesn't sound nitpicky but I'm not sure if the message implied by the gameplay is a good one here lol. The garbage guy basically ditched the job as soon as his bag is empty even though the entire city is still littered with garbage.
If I were to redesign this game... I would reverse the goal a little bit -- the goal would be to clean the streets (while avoiding the Pauls when possible). Since the goal would be to clean the street, there would be a reason to pick up garbage; but there are also some reasons to sometimes avoid some garbage since when the char carries too much garbage his jump is hindered.
P.S. Also yeah. Upon reading some of the other comments I also suddenly remembered I had this to say: Avoid walls of texts for tutorial next time. And I think you have realized the bug that "W" doesn't work.
P.S. 2: I suddenly also remembered this funny interaction in the game I had while playing: After finishing a level the truck moves. In one instance I ended up in front of the truck and I kinda chuckled at the little implications XD
