With pirate and difficulty speeds set to fast, I thought I'd see just how many people I could fit into my super small world. 373 is where I had to stop because of real life pulling me away from the computer, but I would enjoy seeing how other people do on this. Toward the end it did get difficult to keep pirate from chipping away at precious new land before they were destroyed, even with as many towers as I had. I'm sure it's a balance between the number of towers, farms, and of course houses. I also learned that if you destroy a tile, it doesn't just destroy the building on it, but it destroys the whole piece of land... I like that!
Well done on the game Robin, and I agree with everyone here when I say it has potential to be expanded into something even more fun. If I were only able to make a single suggestion, it would be to make the game harder. I have played a total of 5 games of Little lands (I thought it was called Super small world until I just noticed the wording on this page), and I haven't lost in any of them. The first was a little shaky while I tried to figure out what the heck I needed to do, but everything was set on "normal" so the game wasn't overly harsh. I played 2 games with everything on normal, then after I felt like I understood the game I changed pirates and difficulty speeds to high to give it a bit more of an edge. I played 2 games with those settings and then my latest game was this one where I wanted to shoot for a high population.
As long as a game has settings to allow the player to ramp up the difficulty, or "personal challenges" they can set for themselves (like population thingy here), the game will continue to have replay value. Little Lands is a bit light on both of those things, so I think a harder game experience (or a few more settings to help make it harder) would go a long way.
