Level 16 took you forever? And to think I'm still trying to finish level 6. :P

I lucked out a bit on 16, 17 was a little hard, 18 was easy, but I can't do 19.

Here's a hint for 6. Remember, they can't cross, so one has to almost encircle the other.

Yea, it all depends on how your mind works, so some might be tough for some and such. 16 was my personal achilles heel though.

stupid level 15

15 is easy when you plan it out. It took me a few minutes to realize the trick. The key is that breathing room they give you on the lower left side, that big patch of empty squares around the endsquares is your ticket to the hell that is 16.

I can't do 14! :cry:

The only advice I can give is to try looking at it a different way. It's a freakin' clever mind puzzle.

Finally got 19... can't believe I couldn't see that.

28 was also kind of difficult.
