Instead of shortening the timer which may be worse for some of us. An example would be if the price for a certain fish went to an unbelievable amount and we want more fishes for it. So, instead of shortening the timer, I think you should add an upgrade that gives us a better chance for an increase in price.
I appreciate adding $1 to the bar but, as you level up $1 becomes unnoticeable so, it would be very much appreciated to add a couple more $$ as you level up.
Since this is an idle game, maybe you should add an upgrade that allows you to fish automatically but, a lot slower so, it's not too easy. Also, maybe add a reward for staying on longer to motivate us to stay on?
Sometimes the archers can hit my melee warriors and they can't attack back..... I have to send them to the pool or else their just being punching bags.
