Challenge could be added to almost every level. That's why we have different difficulty categories. There is no reason to go back a year later and try to modify levels unless there was an error in the evaluation.
I agree with GIS. There is no obvious challenge other than trying to optimize but even this process seems quite tedious from the beginning. I will avoid rating the lvl as I will be unfair to DP who surely put a lot of effort on this one (the design is indeed a piece of art but the outcome...).
Please recheck this level. I was unable to completely solve it because there were two Green blocks missing. Nice artwork on the design, but this type of level tends to be a little tedious to solve with not much of a challenge.
