Read my previous post. I plan on making the techs for faster foraging much much better, to a point where your foragers could work 10-20 times faster than originally. This should make games that last until the last level much less common.
Yes I will add more tower attack techs to the imperial age. As far as taking it away from enemy - adding armour has the exact same effect.
If you get all the +1000hp bushes, the +10% would be +1000HP +the units original hp, as the 10% adds to what ever the total HP is. And yes it is a huge amount and I wasn't really thinking when I made them, really I didn't make much of a way to make foragers better while the forage bushes were getting 10x bigger. I'll try release an version with new foraging techs today. I don't want to make cheaper vils as they can make the defence easier, and its already too easy it seems. Not really sure how I could add more levels even if I wanted to, I can't add any more HP to the units or they will exceed the max of 30000 with all the upgrades and just die. As I said, too many vils means you could defend easier and that is an issue already. With the incoming forage techs, you would realistically have 10-20 times the foraging speed, so buying 1 would be like buying 20. Still would be better off just getting the techs but I wanted to give people the option. Perhaps will make a new civ bonus of having half price vils.
The whole idea behind the forage bushed was to have a way the team could work together for certain things. Simple fact is most peoples villys are on the forage bushes when the food is worthless, so why would I want to make it even better?
Gold mining is good for getting early feudal age and tower attack. Trade takes time to build up where as gold mining is instant. As far as trade goes, there are 10 different trade units all travelling at different speeds, costing different amounts and carrying different amounts, there is definitely strategy there.

Most of your suggestions make it easier for the player, just remember you also make it easier for your opponents when you do that.

i really loved what you did so far

right now i think game should be improved about the difficulty of defense!
you may think about diversifying the cost of the towers,making them more expensive!
as mentioned in the final analysis all you need to resist without problems until the last wave is a row of about 70 towers!!
balancing the costs of technology you have left a good margin of strategy so the next step could be make the defense harder to be made
why not, you may add to the only cost of rock also wood or gold!!

in my opinion the three towers more easily realizable and effective are the accursed,the axe and the rapid tower, whose costs deviate too little from basic towers, and also are more convenient than towers that would be best but actually are not very effective ^_^

last note:
saracean bonus really sucks ^_^ also mongol trade bird sucks aswell!! i think they both need sumthing more, maybe mongols could have also 2x speed of trade birds!! and saraceans should have a real usefull bonus

you're great man i truly love your job ^_^

actually with the new forage technologies the defense aspect of the game has gotten a lot harder

the axe tower is now 200 stone because it was so cheap against the final rams

I would love to see you make it to the last level with 70 towers with me on the other team. Yes it can be very easy, but only if the people on the other team make it easy for you. I will think about removing some forage bushes and adding more to the standard units, but will need to do a lot more testing to make sure the current set up isn't good enough.

But yes, I do need to adjust some civ bonuses.

Level 24 bonus for bottom team still not fixed - only gold piles spawn
plus in the new version, p6 gets castle age free (either that, or the fact that he was byz)
plus goth house (or p5) costs 99 wood...bug

Not sure about the bonus level bug yet, the spawn triggers look fine. I will look into them all though, thanks.

another guy (was p4) said his byz imperial costed 5k

That is good, byz civ bonus is half price age up.

then fix bonus description, it says 33%, not 50%

V12 Changes:

• Mongols now have everything at the sky dock at half price
• Byzantines now have half price ages
• Goth houses cost standard amount
• Saracen large houses give +1 max population
• Celt bonus decreased to 50%

man p5 mongol is bugged!! i had no civ bonus and i had no foraging bonuses aswell!!! i had +400% foraging and they was as +0%

civ bonuses need rebalancing...atm, mongols, celts and especially chinese are too good

Final level needs to be fixed
We were 6 good players and managed to make it till the end (with all forages taken ofc)
thing is, yes the rams when killed revive, stop for a few sec, and continue. However with all villagers of all players repairing, both teams ended up surviving that level...
