Fun jam idea (Powerwash Sim kind of game).
For feedback: I thought the green smoke visual on trash cans seemed a little out of place, made me think of poison barrels. But the idea they were destroying the leaves kind of makes sense. Moving leaves out of the corners was a problem because of character facing in the corners. I found myself looking at the side of the character a lot, so leaf blower was not pointed with the camera.
I do like what you do with physics and leaf sprites. I thought having a time limit was actually nice...kind of a way to end the loop instead of struggling to get those last leaves (I scored a 'B' grade). Assets, music, and sound effects supported your game very well.
