A nice 'god sim' demo. It was fun to play. Hope you keep developing it.
These are some observations and I understand it is a demo:
I thought it was a little too easy to fend off the raids. Maybe make the boats more powerful and reduce the time between the raids? Maybe they could land and people come ashore?
At the start you have one inhabitant but the screen says 0? I think the info screen needs updating in real time as the money and number of inhabitants stay the same while you are on the screen although the raid time updates.
'Main Menu' (Mian Menu) is spelt incorrectly. As is 'Building' (Bullding).
The raid time doesn't show correctly when it gets under 10 seconds after each minute.
There was the odd inhabitant that moved really slowly and some that seemed to get stuck. e.g. when a house was to be built, no one was doing it yet there were lots people available.
It wasn't obvious that you needed to scroll on the inhabitants list to see them all. And I wasn't sure why you would need to pick certain ones? And as they all had a generic name (base human, human-1), I wasn't sure how you could tell them apart?
The dock only seemed to work in one direction so could only be placed at either end of the island not on the 'sides'. It could do with automatically rotating to fit the landscape.
When you build something it remains on the end of the pointer (so you can build another) but it was difficult to get rid of.
