This is a great brain teaser except i'm decaying because i'm stuck on level 48, i can't wrap my head around it ;_; It's sooo satisfying when I get it right but some levels take me ages. I'm going to keep trying but I'd love a walkthrough.
I also love the progression of "Oh yay we have a dog now! :) Oh right the BLACK HOLES and MINES D:".
Update: OKAY I finally finished it! Felt like a fool when I got it, as with most of the puzzles lol
