Gameplay
Dev want it to be soul-like, Metroid, castlevania, guilty gear, visual novel, and beat 'em up
It's put its ass on many thing and master of none but at least it's not a mess as much as
Seal of lutellaria where to the point that dev forget that They are making a porn game.
Story
simple. Linear. Cliché.
Getting spicy a bit in game over scenes, but pretty vanilla for most people.
Sex scenes
Well animated. Crazy amount of cum. But lack of the scenes of her demise.
It doesn't have to be animated like the other, but it needs to be done to seal the deal and be the real game over scenes.
But with dev attitude, I don't think he wanted to do that to his waifu.
Voice acting
A Newbie voice actress. That's all I can say.
Summary
It's not the dev first game, but they're still learning. So don't lose your head too much and Support them and hope they eventually make a good game.
