I set out to beat the "Robert" guy you mentioned with 980 points, and I succeeded - I managed to get 1000 points!
This is solely because somehow, I got a huge lucky break and when I started the game, a satellite spawned inside the trash compactor. The timer didn't even have time to start, it was at 0 until I placed the trash down.
I had to check the description to see what button used the tractor beam, so I couldn't go in as blind as I prefer, but the game was quite easy to pick up and understand and it's fun enough that I can see people getting quite competitive, trying to get the highest score. Nice job! The audio felt a little bit harsh on the ears, but I got used to it ... though I did also find some bugs.
1: If you're boosting while going into the trash compactor, the boost sound keeps playing the entire time you place down your trash. It was a pain to listen to, so I kept resolving to stop boosting before I got to the compactor next time, but I kept doing it anyway...
2: After you play it once, the main menu stops visibly responding to input. Trying to play again breaks the game completely, as you're unable to move and the timer won't go down.
3: You can stack garbage inside other garbage! You can even stack it outside the compactor, though that softlocks you.
