I played three times. The first time I couldn't figure out in time how to prepare anything. The second time I started to get the hang of it and scored ~190. The third time, despite playing the best, I only scored ~45 - I was really unlucky with orders - got longer once, which apparently don't give you much more rating. You should probably make harder orders give more points/rating and make it so they don't roll in the beginning. My very first order was this long burger and it was intimidating.
