I'm impressed, those solutions are very clever, especially the playroom 4, and greenhouse 12 solves. I never knew that was even possible! The playroom 3 and 5 long jumps were known about but we wanted the star values to not always represent the "lowest" one could do but more or less the best "basic" solve. The solution you found for Greenhouse 9 is actually the intended solution and we put the wrong star value, oops! We'll be fixing that one.
