Not a supporter, but I ran the manual translation file through Sugoi MTL via a script I wrote. Seems to work so far, though the typesetting is off in places (overlapping and runover text).
Unpack the .json file from attached archive and load in the Translation tab of MTool.
For the 3 numbers on the smartphone in the lower left:
- Top number is "Corruption", and roughly speaking measures how much of the school is under your influence. The goal of the game is to get this to 1000 before the 30 days runs out. It also affects the last number as described below. You raise it by purchasing items at different locations on the map, which (I believe) corrupts the girls at that location.
- Middle number is "Alertness", and roughly is how much people on the island have noticed your activities. When it reaches 100 the police are called, game over.
- Bottom number is BP or "Bloomer Points" (I think, translation is a bit wierd). This is the currency used to by items and increase the corruption level. You gain it by spending a period in your room, the upper-right icon with "BP" in it. The amount you gain is equal to your current Corruption.
Strategy involves two snowballing effects. First, increasing Corruption gets you more BP to buy even more stuff to increase Corruption.
Second, if you notice on the buy screens a bunch of numbers in the last column, I
believe this is the Corruption level you need to reach to receive this item for free. So you don't need buy every item, just enough to start the ball rolling getting you free items that increase Corruption to get you more free items.
However, there's an additional requirement to the free items I'm not sure of. It could be something like a certain girl has to reach a certain hypnosis level (click the girl-picture on the smartphone to access this and other personal information). Or it could be you need to corrupt a certain faction enough. It
seemed like once I had a decent number of girls at 50 hypnosis level, the free items started rolling in, but that could just be coincidence.
Finally, there is a mechanism to
lower alertness, but again I'm not perfectly clear on the details. I know it exists though, because my game is currently in a state where every period the alertness goes down by about 5. I'm not sure how I did this though, because it happened after I got fed up and cheated in a bunch of BP and bought a bunch of expensive items.
I suspect the red and blue icons on the item screens have something to do with this, but it could be an effect that slowly builds up so I didn't notice until I had bought a lot of stuff. If that's true, then I suspect red (kind looks like an up arrow) leads to alertness increase while blue leads to decrease.
So overall, I suspect the strategy is, snowball corruption w/ relatively cheap items (not too cheap, since you can only buy one item per period, 150 periods total until game over). Once you're making enough (or alertness gets dangerous) start collecting the (generally expensive) blue-icon items. Once you have alertness under control, you should be clear to further snowball buying items and w/ free items until you reach the required 1000.
