In Irreverent Heresy:
You will immerse yourself in a story where you will be able to control different characters, at different plot points.
These actions will lead the characters to different events; from scenes with less impact (more focused on giving more variety to the replayability), to causing radical changes that modify routes or endings.
Thus, the player will be able to discover a different and organic story, depending on their decisions. Irreverent Heresy is not a harem game!
It is more associated with the NTR; from something lighter and "anecdotal", to something hard and dark.
