love the idea of the game but like someone else said seeing the MC getting fucked would be a nice addition along with some character customization
Just to add because i had the same though about the player character: Adding a free Mode with adjustable KI-difficulty and more different characters with different animation would be interesting over time like a milf-like or tomboy-like would be something or slightly different kind of monster girls.
Also a gallery mode would be great which gathers all defeated characters after you beat them in a normal difficulty and maybe with extra animations like the ending for a hard version.Especially with all the work you have done with the items it would be great to see them more clearly or even longer actions there.
