Nostalgia
As a fan of the original Populos, I want to say "Thank you" for this game.
It's been a while since a played a game like this.
Simple, quick fun, but with so much depth behind it. It allows for a multitude of tactics, and could be a real burner in multiplayer.
Perfecting the "easy to learn, hard to master" design mantra, you made a good homage to the original, with enough new ideas to get me interested.
Kudos to the AI, it is mostly rather competitive.
I'm a little sad that building high and flooding the enemy doesn't work anymore because the Ai totally abuses my lag and casts flood two more times.
And I miss the volcano, though in retrospect I can't even tell what it did.
The controls drove me absolutely crazy, what with suddenly planting a mountain in my territory when I click twice, and I had some serious performance issue. This game would work a lot better with a zoom option, or a bigger window so a worldmap can be fit, but just like the controls, thats the limits you have, and I'm unwilling to draw any points for the platform.
As such, 5/5, 10/10, and keep going!
