A very enjoyable game, more so than most. I would say it is better than pretty much any free web game and even better than some you'd pay for.
The gameplay confused me for a couple minutes because I wasn't pressing the space bar like I was supposed to. But overall this is a very fun game, even if everything except the basic burger and the hippie burger have cheese on them. :(
The campaign mode seems promising but the high score page is broken currently. When you try to submit a score it will just lead you to some generic landing page with links to dozens of "top games". Perhaps someone bought out that URL since this game was made?
Also the total amount of content is a bit low. But despite those gripes this is one of the better games on Newgrounds and I would recommend it if you want a game that is easy to get into and doesn't take too long to complete.
