The cake look delicious, but it also seemed to have little teeth/horns in it, which was a cool touch.
This was fun! You have made enormous progress into 3d development this year. I think I agree with some of the other posters that the shooting was not super satisfying. But for me, that did not really hamper my enjoyment of the game because of how compelling the "collect-and-defend" loop is. It's really exciting to see incoming enemies and gauge whether there is time to grab that last cake before scurrying home to defend your slimy baby.
Your world was a little empty, but all of the assets you did create look awesome! The animations are all extremely charming, and the level design was reminiscent of the classic Quake 3 deathmatch arenas. And similarly, I felt empowered to use verticality and make huge jumps between platforms as I scrambled to fill my green child with frosting.
