Very cool aesthetic and nice choice of background music! I'm impressed at the level of visual quality you were able to achieve with just a couple days.
I agree with the other commenters that visual/audio feedback when hitting ads would have helped the game feel more responsive.
The camera change was cool, but consider that the overall gameplay doesn't change that much: in both phases of the game, the player needs to click on moving targets in 2D space within a limited time span. I would have appreciated some kind of new mechanic that pushes the player to build upon what they've already learned to do.
I also didn't realize at first that you were supposed to shoot the purple circular ads since they have the same face as the green one you're not supposed to shoot.
