Ok i have got to one of the endings (prostitution).
I like the game, but it is buggy and grindy as hell :
1) the corruption points can come back to 0, just because the game feel like it (no need to pray)
For example, sometimes you can suck a banana 8 time in a row (minus 80), and the tomorrow morning its 0 again
2) some necessary events must be done at a fixed days with a fixed time. So you may grind weeks and week for nothing.
For example, the "parties" must be done on Saturday after doing a bit of gardening or cleaning at the church but before the father prayer.
3) from the ending i have got, there seems to be six available paths (uncle, father, prostitute, homeless, good girl and a strange "church of vice"), but there is no tips to easily choice between then endings. I suppose than for each ending there are a places you must go more often than others.
The main problem of the game, is than it's a fake free roaming game with fake stats and many bugs, when it is in fact a choice based game with hidden stats. This game need an un-bugged version to be a bit more playable. That said, i need to find the "church of vice" path...
In short, there are worst games out there, at last this one have an ending, but there are far better games too.
