Well...
Neat! This game is the shizzle. I drew a solution to level 12 if any body is stuck. It took me the longest to figure outm and it really is one of the easier ones to do. (hint: the exit you think is right is fools gold, shoot for an out of the way spot)
for those that want the instant gratifacation...

The game is really well thought out. maybe a good twist would be to have "boulderdash" style ellements in the next version. like if you pass certain blocks they move, or have tiles that switch portals on and off.
