You can get a builder to go up that high on "Sharing a climber?" It looks impossible... Maybe I'll try it...
About "Floater's Round", what do you mean by this:
one building down from the top fire pattern,
I guess I didn't find the level quite as easy as you did (Of course it is not very hard), but I played it a while ago... I don't see more than one real possible solution with one possible variant (which is nearly identical)... The builders are the limiting factor in this level of course... other tools are plentiful...
Well, moving on anyway (But I am still curious about your alternate solutions to "Floater's Round"):
Garjen00 - Level 10: Printing Press
A0; A0;
80 Lems A0;
98% to save A0;
RR: 1
Time: 9 minutes
Skills: 20 of each
Good: Nice level design. You have to think a little how to manage the four different groups. A good level to be at the last level in the pack.
Bad: Long and tedious, without any real puzzle to it.
