I like the theme of being a restaurant and making burgers  using the different ingredients  and hiring chefs for you to help. The incremental mechanics all work great.  The music is and art is fitting. The thing I would say to improve is implementing a way of improving the speed of producing the burgers. As other people have said, the prestige target is way too far off for me to consider trying to reach, but nonetheless a solid game.

Use of the pizzatron theme is godly. Using the ingredient mechanic along with buying an upgrade makes it very similar to cake clicker. The upgrades here have more function but the production of burgers is still limited to 1 + your click speed. Even if you use an autoclicker that would click 50 times a second, that's over 200 days straight for prestige 1 and you can miss me with that. Great game otherwise.
