snake maze (8v)

a variation of this http://www.clickmazes.com/quantum/ixquantum.htm, in that every step you take will create obstacles that hinder later movement

I think it could be np-hard, but too lazy to prove it ... by the time I got to crossMaze.png I gave up on trying to make the level layout compact

once saw a paper about how sokoban is pspace-complete http://citeseerx.ist.psu.edu/viewdoc/download;jsessionid=2220782E689C32BDC579ADA...

but it takes 4 of these big structures just to make a crossover. oof
