I was totally scared by the comments, however, glad me, I found it pretty fast. Not because I understood it but just, out of the routes I tried, one suddenly won, purely by luck. :D

Tilu

S for Snake

Very interesting one that needs to organize properly. However, to be honest, between 2 off route and winning route, couldn't noticed what I did different :D

Groping for a Dropped Contact Lens

Wooow, that 66 is a great find, by hi19. I enjoyed looking for it. :))

Pretty neat despite your route being broken!

Reach

Reach's 68 route was more interesting to me, but either way the level is conceptually very interesting and I really enjoyed the solving process.
