Loved, the worm, loved the idea and the mechanics! I had some trouble climbing up the wall, as the second worm didn't seem to be able to "hold" when it was above the first while the first was holding.
Hm, was there a bug with the game or was it just difficult? You should be able to hold with both worms at the same time
Damn! It must have been a bug on my end then. I'm playing on Linux w/ Firefox so it could totally be a compatibility issue on my end.
