It's fun, but the fact that any contact can kill you makes it way too easy for smaller snakes to blitz out of nowhere and kill me.
Although many of the things in it are fun. Making a giant snake, surrounding people and slowly encasing them, the mad dash when the first person dies...
tried it yesterday, the idea is not bad at all, it has actually some better features than Agar.io according to me, unlike Agar.io this game avoid people teaming up and "farming" endlessly (right Death/Riv? ;) ) it is actually way easier to destroy a big one.
I had some lags, but apparently I read they are planning to open new servers to this game, so as it is, it is a very promising game :)
It is a bit more rage inducing. In agar.io , when you're big, you can lose half your mass and then build up from there. In slither.io , you can accidentally butt into some tiny worm-lookin'-thing and lose everything.
On the plus side, it's waaay easier to get bigger in slither.
I will eat you Belgian, and I will invite my good friend, Maggie De Block for this great dinner, Belgian en sauce with garnitures aux fromages! mmmh exquis!
