This is an excellent arcade-style game! I worked hard and my manager rewarded me. Truly, this is the best game about the folly and fury of supply-side economics and so-called consumer-discipline. This game made me a communist.
But in all seriousness, about the only thing I would add would be pick-ups: a big funnel to catch more things, a mouth-widener, a health-pickup to make it harder for my boss to fire me, an orally-mounted vacuum tube. Just something to help keep the variety up (though the items do an excellent job as it is!) and to help with balance once the game really starts throwing things at you.
But with that said, excellent work! This is one of my favorites I've played hands down. Keep it up!
