Hey dude, I formatted your post for easier reading.

I really like the premise of your game. I played to get level 3 on all buildings and am basically nothing left to do at this point. Here's my thoughts:
1. On the one hand, I like the brevity of the game, but if you're looking to turn this into a longer playing incremental, you could slow it down a bit. I started playing for a couple hours and had gotten a long ways, but after letting it run overnight, I now have basically infinite resources. Like the Kittens Game, you could control this by adding some kind of material storage that limits what you can accumulate - this would make the game play slower and possibly add challenges as well.
2. I think you should expand the game with more technologies and add quests. To this point, you're basically trying to get enough resources to build ships, but what do the ships do? Maybe you should have many islands that people are trying to populate by building ships, sailing to a new island, and starting over with a new / more limited / different set of resources.
3. I like the idea of having different starting / limiting resources as a way to challenge players more. Maybe you only start with one or two forests, and you have to develop technologies, plant seeds, whatever - as a way of getting more forests, which allows you to expand your resource base. This would be another way of creating challenges or quests for players - maybe after you get some number of forests, you get a bonus - something like that.
4. I like your artwork, but it's not that clear to a new player what a mountain is, what is grass, etc, or that you buildings work diagonally to a resource. Also, it would help to have more information about a resource - for instance, you don't really know how many people all your buildings require vs. how many people you have - you just see that some buildings aren't working. Having better information about people / resources would help players understand what's going on better.
5. I like the idea of requiring water for your population, so maybe you can only initially build houses by the water, and later, you develop technology to construct a lake around which you build houses - and you could have more types of larger houses to house more people. 6. If adding more types of technology, many games require you to get things like coal where you combine coal / wood to get iron / steel / etc - you could add more resources and make it more difficult to get higher levels of technology that require a lot of complex resources.
