When I started to play Kapilands (about 3 or 4 years ago) it was a brilliant game where profit was only made by players who really knew what to do and, on a side note, you could buy Wood, Power, Water, Stones and Steel for less than the pointless Communist/Socialist Republic prices we have on here. Now there is no challenge, but nevermind, that means we can all have what we would call in the UK: 'a piss about'.
Anyway, my suggestion was for more advertisements all over the internet. I NEVER see a Kapilands advert when I'm just surfing the net these days, whereas 3 or 4 years ago the web was literally crawling, littered with these adverts for the game! That's how I heard of Kapilands... through looking for a guitar tab on Ultimate-Guitar.
So my suggestion is (since you make a fortune from 'coins' sales): Advertise more - the game is boring, and it's really just down to the faithful few. Nobody can deny this. It's not a patch on what it once was.

EH.
