All you do is click F and J, and the game is hyper-political. Weak graphics.

Yeah. Just tap alternate keys and see how far you can go without passing out? Two big problems. First you can't get past the supervisor unless you're on red. Second there is NO level of work which won't drain your health, or regain it. I got 3.65 yen by working at a conservative pace except when the guy comes.

Look, this game may be informitive but that's no excuse to break the laws of conventional gaming. First and foremost is that people should feel rewarded playing it.

I made 1 ¥ and then passed the hell out!!! Food for the whole family!!!!

Controls, nothing more than just alternatively pressing two buttons. But hey, there's actually a way to play on without getting caught or passing out, while also getting good score per second.

The current productivity level in which you're at (the vertical bar) has three functions:
Firstly, it determines the amount of money you get per second.
Secondly, it determines how easily you'll get caught and kicked out by the supervisor (red, at around 70% of the bar is a definite pass; the supervisor will leave you alone. any lower and the supervisor will get suspicious, with time taken to kick you out decreases the lower your current level of productivity.)
Thirdly, it determines your loss of health over time. At the green zone (below 50%) you recover health. When it is yellow (between 50% to 70%), you lose a small amount of health per second, and when it is red (between 71% to 100%), you lose a lot of health, with 100% being the highest loss over time.

With these mechanics understood, the way to safely keep yourself playing (or at least, until you get bored/tired and go do something else,) is to keep your productivity at yellow, shift it to red when the supervisor comes, and when he leaves, lower it back to yellow. If your health is at 50% or below, lower it to green, just slightly below yellow, and shift it back when it is full just in case the supervisor comes back.

Doing so will keep your health in the safe levels to carry on playing the game. The reason why keeping the bar at yellow when your health is okay is because going any lower will take too long to raise it back to red before the supervisor kicks you out, ending the game.

As the difficulty never shows any signs of increasing throughout the course of the game (maybe your fingers will get twitchy, that's all,) it is actually possible to keep playing this game on infinitely. But who'd want to actually do that? There's definitely a better thing out there to do with your time.

Unless....there were medals, or a high score board or something...

Great message conveyed in this game, overall. perhaps a role reversed version of this game would be nice, playing as the supervisor instead...? It would be fun, having to find a good balance of kicking and keeping your "slaves".

the message is clear. after a while you get a routine going in it become way to easy and repetitive and got bored and stoped.
