Cool little game. The controls are a lot more robotic (tank-like?) than the readme makes them out to be. If you wanted to add more depth to the gameplay, consider adding a bin to deposit held rubbish. Or steal some ideas from Viscera Cleanup lol.
Overthinking things: The depot in the middle has a total of eight doors. I have no idea how the inside is structured.
At the end, I found that without the light pollution, a faint shimmer of stars can be seen through the smog. That’s a nice touch, but why can’t I clean the sky. My arms are too short. Give me longer arms.
