I really liked the concept of the game, I think it's a pretty cool idea. That being said, the graphics aren't the best. Don't get me wrong, a game like this could work with very simplistic graphics, but if you're going to go with just colored shapes in your game, try to make the colors complement each other well (color theory). The hitbox for the "player" that follows the mouse is also very off, and the box itself probably isn't really needed as you can see your mouse cursor anyways. I see you submitted over 4 days before the deadline, that's some time you could have spent making the game feel and look better. Other than that, cool concept :)
