Had a fun time with this one! My only comment is that, since we are talking about webbing, my web lines should be sticky enough to trap the flies. As in, I could shoot out a web and any flies that hit that line should be caught, not just the one at the end. I was kinda surprised to see that wasn't the case. You'd likely have to balance the game differently so it wasn't super easy to catch flies, but something like that would sell the idea of it being webbing you're shooting out instead of a generic tether.
Other than that, I had a good time! I'm a bit afraid of spiders, but this game kinda grew on me I guess!
