I hate easy level. You have to rely on getting lucky with the destiny tiles and get extra moves. There just aren't enough 20 point tiles otherwise. Hard is less stressful, just avoid destiny tiles at all costs, hope for a lucky break or two with a transformation tile or old dreams and if you find both question tiles, you can get 700 fairly often. But what you say is 100% correct "gotta keep trying and hope you get lucky."

...and getting two spirits on an 800 score...that's awesome...well, if they were needed that is.
