Very original ideas. You did a good job in the voice acting deparment, though you really need a better microphone, as the audio came out a bit choppy. It's fairly basic, but you're a 1 man army for doing sound, coding, and art all by yourself!
The SFX from clicking where very loud on the conveyor level, I think this is tied to the fact that I can hold the mouse down, and have it loop. For a game like this, you'd probably want to make every "smash" an individual click, as opposed to holding.
Good job, you have a lot of potential in game dev, esspecially considering how young you sound!
