maybe too late. but its best not to focus on the bronze age, its best to put all your effort into rushing the iron age, and then getting your 4th house. then focus on upgrading stuff (while you still have a 24 hour free protection)
3 towers and walls wont save you from a realistic raid, as higher level players will pray on you
You need a catapult ASAP and then stables to protect you from soldiers
although you will almost always lose if a greek / french player raids you until you get to the medieval age
you dont compete against others who are only at your level / age
