I logged in this morning again for a quick game, and it appears you've considerably shrank the "worlds" into smaller spaces. The game has changed completely for me, as it's about 50/50 that I will survive the first 20 seconds. It's gotten extremely tight in there and there's no more room to maneuver. If you're a big cell, it's almost impossible to die, as there is now always a stream of little guys that get trapped, then sucked in.
I really had a lot of fun "exploring" the worlds and occasionally bumping into another cell, or just crossing paths yesterday. I could go on long chases that would last a few minutes, which was a lot of fun. As of now (I tried the 4 regions), it's basically a reflex game. Splitting in half to "attack" I think is the cornerstone of this game (if you want to get big, you have to risk a bit), but it's so crowded now that it's prohibitively expensive/risky to do so, which sucks.
A small thing to consider for user retention: if I've carefully built up my cell to a respectable size, I will try to play smart and not leave my computer, grab water, go to the washroom, because I'm invested. If I die every 3 minutes, it's easy for me to drop it, forget about it and move on. I spent 60-90 minutes in a single game yesterday, and didn't want to "lose my work", if you see what I mean.
Awesome work (I think the small upgrades on the theme, names, etc. is awesome), keep iterating - but I think I'm going to get back to productive stuff now, because the game has lost most of its appeal to me.
