I was going on easy to see how far i could go aiming for 4 thousand. At around 4300~ i wanted to lose so i stopped going there upgrading. It is at aver 5560 now and i want it to end. Of course i refuse to give up. Giving me the option to call more waves at once would help. (espesialy at begining after a lot of upgrades on blueprints)
Make a broken glass armor when glass armor brakes, so you can fix it with gold at heavy expence, so you dont have to farm at the same map all the time.
A wepon level up and prestige system. I want to level up my wepon even by 0.000% Chance so some weapons get better. Like 0.5 chance to stun can be uppgraded to 2% at max, where you prestige for xp or gold or some kind of weapon point system where you buy other uniqe weapons.
Some kind of bank system? Like you may get robbed now and then but you may put money in the bank for a small % rate and they give rent for a very small %rate?
Maybe in the future you can make a mercanary shop? Like a hiring some mercaneries that are stronger cost more and they help you farm and with raids for XXX time?
I would love to buy a small shop or a trader, that gives some passive income. Not like buy 50 and have huge amount of money i mean one or two diffrent kinds that you buy one of.
I love this game, can you make a secret item hidden on one of the farm maps? And there is a bug that "someone walked into your base" but noone not even merchant is there.
