Hello.
I had a couple of problems understanding how the game works, so maybe you could make a tutorial?
It seems like each time I die/lose there is no instruction to restart. I realllly recommend you adding instructions on how to restart on future games.
It also seems like the scrap spawns off-map sometimes, so I cannot pick it up.
The way that thing on the middle ( where you deposit the trash ) is complicated. Maybe some kind of instruction of like: when you are near it a big E appears, so players click the key E, could be good.
I like your take on the theme and pixel-art tho.
