Just found this game, here's my guide for anybody who picks it up.
First, this is a rogue-like game. It's designed for you to fail, but you get to keep money to spend in the shop to add girls,have sex last longer, get more clients per day, etc...
Each day, you will see 3 girls (4 with the perk)
At the end of the day, you will lose however much money is in the "CREDIT" box.
If you have surplus, it goes into savings to spend later from the title screen.
Each day the amount of CREDIT needed will increase.
IF on any day, you don't have enough to cover the CREDIT, game over. Back to title.
Tips:
#1 Once you get into it, you can get a feel for how much per girl you can make based on the perks you have at that time.
Basically, after your first girl on first day, you know about how much you can make.
Multiple by 3 - that's your rough max total per day. If on any given day, that total and the CREDIT are close to the same number, plan to throw that day and lose. In fact, if you are only going to make a few 100, throw the day at the end. You don't want to have to do a full day you know you will lose and only have a few 100 to show for it. Better to get back to grinding the early days where you make the most money.
#2 as another poster said, you can hit all three directions (there's no right arrow I've seen so far) at the same time and it works.
#4 Once you get to about day 4 or 5 and can bank about 10K for those 4 or 5 days. Do a run or two of buying girls and clothes a few times only - at least if you want it to be more diverse early on with the vissuals. It doesnt take long to only do 4 or 5 days and you can do several pricey things at once with that much money. Then proceed like normal. At least that was my strat.
#5 If you can keep time (music) doing the tip above and having good time keeping, you can string perfects as the timing is very regular.
There is an unlock button if you want to unlock everything (at least in the version I got, I bought from DLSite)
It says "censor" and I guess it kind of is. HIs dick is so small compared to the bodies (poor guy) it's barely noticeable.
Happy frapping.
