Save1 - "SaveAllEnding" is the save at the beginning of the 6th run, after all endings are open.

Save2 - "SaveLastFight" is a save at level 11 in the room with the secret documents; just take the documents and leave the room. You've got all items so if you want to just see the escape, easy in this save.

Save3 - "SaveVirginFirstDayEscape" is a curiosity, where I managed to keep her a virgin while getting all the stuff to escape. Doesn't have the key or the documents though you so only Ending 2. I wonder if "God's Punishment" would be useful if you got the key (but need so low Purity for the Bum I'm not sure if that's possible...).

Oh, and small table of Purity limits you need for all the options I gathered:
Fuck people in their homes: 80 (starting from)
Fuck people in the pub: 60 (starting from)
Fuck the mayor: 55?
Fuck the bum: 50

There's also some purity limit where you can start going nude, etc. Haven't paid too much attention to those. Oh, and one thing about clothes; the more clothes you wear, the higher your defense but the lower your offense.

For most fights, if you aren't in it for the scenery, you usually want to wear next-to-no-clothes to maximize your offense. Of course, higher defense = more fun. Note that if you go outdoors without panties the two enemy groups (4 enemies but you fight 2 at a time if one of them catches you) will chase you and attack you.

Only really difficult enemies are the drunkards (highly resistant to everything except riding, low chance of cumming) and the last fight. The rest are pretty easy to deal with.
