Nice simple little game, hope you learned a lot of new things on this project. I think as simple as the game is, it is still quite polished with the art, sound effect, particles. I think it would be nice to add more variety in the things that fall down, maybe some multipliers or damages. Different speeds of falling objects could help too. Also I would like to have some way of speeding up the gamespeed if you are already in position. Overall, great submission!
