Reviving this thread with results for
Blitz:
L: 1, 3, 6, 7, 8, 12, 14. 100%: 1, 3, 6, 7, 8, 14. Non-100%: 12.
R: All. (Yes, every single level, without glitches!) Non-100%: 12, 15, 16.
A few notes:
9R is also a builder+digger 100% solution, which hasn't been posted on the fewest skill types thread yet. Two for the price of one
14R just takes a bunch of miner backstrokes and digging when the lemmings turn around.
15R is the standard climb-bomb-bash backroute, requires extreme precision on the bomber.
16R has already been achieved in my
1-bomber solution, another two-for-one
Attached replays for 1L+R, 8R, 9R, 10R, 13R.
