Do you need a walkthrough to play this? Like, will I miss out on scenes or get forced into routes I don't want if I don't havea walkthrough? Because needing a WT is a really effective way of removing most of the fun from a game.
Unfortunately this game is mostly dependent on the walkthrough.
Dev makes an excellent official walkthrough that is updated every release that ends with 0.
so
0.5.4.0 - new walkthrough
0.5.4.5 - no new walkthrough
0.5.5.0 - new walkthrough
etc
Normally I really dislike such games...
But here it works out well I think.
There is tons of content and variation and choices and by and large the walkthrough makes it clear of the myriad paths for you to choose from.
there is interactions based on your corruption (rarely), girl corruption, girl relationship choice (love/lust), NTR status (netorase and netorare. with setting toggle to completely disable it), and the individual quest routes.
Although to be fair, most sex is gated behind corrupting the girls.
Corruption typically has 3 dialog stages. with different dialogs at different levels of corruption.
