@bunky, wolverton - I've encountered a bug where sometimes the game appears to think that the control key is being pressed, and no amount of pressing or releasing left or right control will clear it. I have to reload the game to fix it.
@alchemie - I have the same problem. I wonder if it's related to the event - did you get all 3 medals? I filed a bug report, so let's hope it gets fixed soon.
Surprisingly, the first level is one of the hardest; once you start unlocking genes and prioritising str, def and repr, it gets very easy. Unlike many games of this type, best bet is to go for unowned cells first as quickly as possible, and then attack enemy.
Anyone know how many levels there are? It would be helpful if there was some indication of how far through the game you are. At least it remembers what level you were on when you reload the game.
Each day lasts approx 70 seconds, so with clipsize of 850, minigun can fire all day continuously (at least until it bugs out and stops working :-( ). For shotgun, spam reload (spacebar); with clipsize of ~40 can then shoot pretty much continuously (thanks Qgon). All other guns are waste of money.
If you're stuck on the windmill, just look at what information in the room you haven't used yet, it's pretty straightforward. If you're still stuck, there's always the walkthrough...
@Changeling - try clearing the browser cache - I had to do that to get the game to run after the last update. Only clear the browser cache, don't clear the flash cache or delete cookies etc.
The boss only teleports if you run past him, so easiest way to kill him is with the staff - shoot him and back away, and he'll keep walking towards you. Don't forget tidal wave every time you can when the boss is visible. With high def/movement/evasion you can mostly walk through the other mobs.
Other hints: always attack if enemy attack level is low, as this will boost your defence by 10% for minimal cost, else if enemy cunning is low, then cheat, else if they come to enslave you then flee. Building the mine seems pointless as it costs the same as half the pyramid, and by the time you can afford it, you're probably getting ~150k production/turn anyway, so will get the pyramid in another 5-6 turns. Mysticism/poly/monotheism don't do much for you, as, if you concentrate on population growth, most culture will come passively from population rather than active worship. If you lose people, or get drought in the first 30 turns, it will probably be more efficient to restart.
The trouble with this game is that it penalises early expansion. In most civ games you want to expand population and research as fast as possible, but here, because technologies are locked until a particular date, and later tech is much better than, and the same price as, early tech, and because of escalating costs of research, if you get too much early tech, you can't afford the best stuff in Age VI. So, for an easy 5* win on hard, in Age IV, aim for 155 population and cultivation lvl 3, and single points in other tech, carrying over ~8 research to Age V. Then aim for lvl 5 in irrigation and stonebrick and single points elsewhere, to give 11k pop, and at least 12 research to carry over to Age VI. Then you can immediately unlock a bunch of tech, concentrate on growing population, and have pyramids by 2600.
