Good work! There's a lot going on here and I can see the systems you created.
My only suggestion for the game is to add a basket or paddle on top of the guys head so it's clear where players need to catch the cat/baby/dog. It's hard to tell where to line up the player to catch the object.
Also adding a drop shadow to the player character and falling objects would make it clearer where to position the player as well.
I've never played a 3D falling object game, so this was a cool idea
This being your first game, I think you covered a lot of bases. Audio, particles, and 3D controllers are not simple to handle and you've implemented a lot of systems here.
