Thanks. I'll see if I can come up with an interesting idea to make the game less difficult. But not right away; I need to take a break from this game. I shouldn't have released all the versions at once.
It really is terrifically good on all formats. But by the time you need 60 out of 64 items on the final part, and some of those items are indestructible rocks, sheesh! :D
(My solution does seem quite a neat one, I think - get rid of them if you can take 4 or more out at once. That way it's tactical, and three would be too easy. Or just set a hard cap of maybe 50 for the final section of the round - that's still pretty hard, and it'll still keep getting harder because you'll run shorter and shorter on bonus pieces.)
