i liked this game. very good use of the theme. the story reminds me a bit of mine, actually, we even thought of the same "explosive" inconvenience, if you get what i'm saying.
that being said, my brain just melted having to pay attention to the trash piling up and at the same time checking if there were bombs coming. i think it'd be better if you added some really noticeable indicator when a bomb has been sent to you and it's about to explode, because, as it is right now, i think it's too difficult.
also, on that same level where bombs first appear, you introduce a mechanic where you have to press buttons to get the correct bin and it all piles up and acts as a difficulty spike that's a bit hard to manage as a player.
