At some point the throwing thing got stuck outside the screen, it came back on its own after a while.
One time the screen turned redish and stood that way until I restarted the page.
The throwing feels nice but some falling objects seem impossible, even if they weren't try to reduce that feeling on players.
It's too easy to click outside the screen causing getting trash.
If you are planning to continue developing the game you could consider powerups, score system, different vehicle options, levels...
Overall, Good job!
