Truly superb.
This game is honestly my favourite submission to this date. It's such an immense concept and has been pulled off pretty well. However, I feel there is a slight awkwardness to places and needs tewaking, in my opinion. I'd love to be in on the project of the game, just to see how you've done evrything.
A few things I feel need slight reworking:
=> At first, I was going to suggest you rework the webbing into a reticle "turret" like function, but after many thoughts, I preferred the method you chose. One thing that could be improved though, is attatching the second end, which can be quite tricky or tedious.
=> Well, I can't think of a way of fixing this, but moving can be a bit tedious at times. I was thinking, a way to make your feet non-sticky. Such as, lets say, if you hel;d shift, then your feet ould become unsticky. so if you were on a ceiling you would just fall off. That way, you could use just one leg to sort of leap place to place, or choose to do it the normal way. I'm unsure about this one, maybe it's just the speed of my computer, it does seem less tedious when the settings are low.
=> I'd like to see many more ways to incorporate webbing functionality. It was great going through the game again, making intricate web traps. It's be nice to make traditional spider webs. This'd be cheap, so maybe only set to certain levels, but seeing some more ways to play with the web would be a great feature.
=> It can sometimes be annoying when you're trying to hold something in your mouth (or eat something/attack an enemy) only to have your body move out the way as you get it near your mouth.
Other than those points (which are really only my personal feelings, ignore them by any means) this was a great little experience and hope to see further development of the game. Maybe make a series of Tri-achnid games or something? I hope to see this go far.
