I have no idea how to play this game and how things work.

I really didn't know how to play the game but art was GREAT.

it lacks of explanation, otherwise the art is really polished and the gameplay is good.
30 000 points, i think the red button is a lil broken ;D haha

I wasn't sure how to play to game, and found myself looking for instructions. The main menu looked really nice!

This was fun, good work! I was confused about the controls, but I figured it out, good job!

The art and sound design are great for a game jam, working with the theme very well. The only thing I wish was added somewhere is the controls for the game. Unless I just couldn't find it.

I liked the robot and sound design, they were well fitting and cute.  After a certain point if you fill up the grid you can just press space in one spot indefinitely and push your score into 6-7 digits until you get sick of pressing space.

I'm going to be honest, the main menu is the best part about this.

Can we have the robot be dodging cars, and if there is too much trash, you lose?
I recommend putting a dark (I would say black) background for the score stats as well.

All-in-all, well done.

Great idea, whats more it encourage recycling !
