If you put the game on low quality for a while, then turn to high quality for a few seconds your IPS will skyrocket, put it back to low when it's at its peak and you'll actually get that income. Can increase income at least 20x this way.
The sad thing is that much simpler games end up much funner(and higher rated) since decisions actually matter whereas this game is trying to be complex but just ends up as a crap shot. Good example of either do something right or don't do it at all.
The game does have some potential, but is held back by some very poor planning. I noticed the developer's reply about the upgrades and laughed they didn't want people making a random choice so you can swap back and forth... riiight - but you can never see damage numbers so basically it's still just a random choice which upgrade might be better. Maybe there is no difference and the upgrades do nothing? One poster pointed out that the Hunter and Sniper have same fire rate - maybe they do and it's just the illusion of a choice for game "depth".
The end.
On trying to give this game a second shot I downgraded from 3 (for hidden stat caps on characters) to a 2 since also apparently recruiting is just dumb luck... or maybe it's just necessary to plot out who you can recruit on what day... day 5 = all common spearmen, day 6 = all rare archers? LOL. Either way rather than being about strategy the game is just press mostly random buttons and you'll maybe get lucky, or slowly plot out the best course over 10 replays as I think most people do.
It's fitting that the workers all push a button all day since that's all the game is, button mashing. There is no strategy or anything to optimize. You have unlimited money even if you set up the building terribly. Just click offices-upgrade, click workers-promote... over and over.
