Nice game! Had a bit of fun (especially with the green slowdown effect splitting everything into 2 colors). I do have a design note though; right now in the game there is no real reason for the player to put themselves into danger to get more points, as it is easier and safer to stay in one spot and only get pickups that are near the mouse. Having some reason for the player to want to engage with the game/obstacles besides getting bored would enhance the gameplay.
Good stuff again
