I just got the last programming-related achievement (completely on my own, zero hints except for the list of professor-beatable levels, with only "Score 40 in Pangu" left) and as much as it is tempting to just look how the shortest solutions work, the ideas I came up with while completing "Beat professor in 10 levels" achievement were so interesting that I expect many other levels to also contain some ingenious ideas worth discovering on my own. Which of the professor-beatable levels do you think I should...

That's the only achievement I have left. I don't feel like figuring this out on my own. The required 40 seems to be much more than 27-31 I previously achieved when winning. So help/hints/strats is appreciated.

According to chapter 6, every problem can be solved without keywords. But, I could not solve 4-1 without keywords.

I found a would be 8/13 solution for 4-15 (Expansion). It "would be" if the game didn't have a 255-length limitation. Because of this limitation, I needed to do extra tricks and it ended up being a 12/13 solution. I tested it for all 6 string-length, so pretty sure it is correct, but most tests takes take over a minute each, so it's too slow to get the game to acknowledge it's correctness. # a$b$$c$$$d$$$$e$$$$$f (length: 21) # 0 + 1*6**1 + 2*6**2 + 3*6**3 + 4*6**4 + 5*6**5 = 44790 # Longe...

I do not have the user manual PDF's in my game download. I have tried reinstalling and verifying game files but cannot find the manual files. Is there a way to download them or find them somewhere?
