Wow... I skip coming here for one day, and look what happens... 3.2.6.1 released, and 2 more seasons of these! I'd better get to work.
#11: I actually havn't solved this one yet. I know the trick but I need to think more anyway.
#12: I got this one second try... blew up the snik snak too! 129 points! Fun.
#13: I got all 4.
#14: I did it, but I stopped to think.
#15: The ones outside were easy... the ones inside kept me alert
Overall, I think 12 is the best puzzle, 14 or 15 the most fun.
BTW is 'deadly when colliding with' off on ALL of these? What about for electrons? #13-15 especially would work either way...
