Ok, regarding the past comments on my levels (college, ok? I have a very light day today, fortunately)...
Spelling errors on levels 3 and 5 -- I won our school's 2nd and 3rd grade spelling bee. In 5th grade, our spelling words were kindergarden level. No joke (Spell "up". ... Use in sentence. Like, I really wish I were making this up.) and I forgot how to spell. So, ya, words like quandary and persistence are hard for me. I should fix those one of these days.
Save percent on level 6 (5/10, instead of 8/10) -- just a red herring, no more.
Precision in level 7 -- I've had no problems with precision in level 7. I've passed it 4 or 5 times in a row without TOO many problems. Yes, I need all the builders every time, but I don't think I've ever failed the level.
Levels 13 and 14 -- I didn't think 13 was significantly easier than 14, honestly. Easier, definitely. But I don't think the route is THAT obvious. Or maybe it is, I don't know. Yes, I want the levels next to each other, though.
Difficulty of 15 -- Ok, in hindsight, this is a somewhat easy level for middle of the pack. Part of my reasoning is that a lot of the earlier levels are "1 of each" levels, and I didn't want to flood the beginning with them. Then again, all the Lemmings games have a lot of disproportionately easy levels (Taxing 29, anyone?), so... ya.
