Hmm, this one is absolutely brutal. Not sure what I'm missing here, but I got 2 off pretty quickly but from there have found about a zillion 2 offs but no 60s. I'll put it away for now.
However, the design is really interesting and the fact you can set up that many 2 offs with this is pretty wild. Great stuff.
Woooow! It does have an intense effect on the eyes. For me it was hard to watch, but I managed. Took me about 15 - 20 minutes, to find 60. Very good and interesting level, imo.
