well this was fun, if rather difficult. I kept being surrounded by only small patches of buildings as the population was getting very high, and not being fast enough to counter it in time. Not helped by me being unable to really get the hang of the way it "snaps" to tiles rather than being a smooth transition.
The only thing I could say felt kind of unfair was when the building would connect far beyond what was on screen, a few times I went from 90+% all the way down to zero just clicking on one of those swathes of buildings.
This game was a nice reminder of FLCL and how much I enjoyed that show. (and I must admit I lost more than a few games trying to look for Takkun in case he was in that part of the game.)
