Ok, there seems to be a lot going on in the reviews.
So this review will be entirely about the game, not development or similar...
So first off, the game is pretty unique, It is a turn based side scroller. Its gameplay revolves around turns, and actions, each turn you can perform 2 type of actions, those that are before the turn, and after the turn. Before the turn, actions are effective immediately and are undodgedable, or uninterruptible. After the turn actions, leave the enemies time to do their before the turn action. It feels different from the normal game, but nothing too outstanding.
What is outstanding thought is the lewd part. It has your usual side scroller things, like grabs and on loose scenes. Where it truly gained for me, is that when you get grab, or lose and get the ending scene, you get corruption. Each race in the game have their own corruption, and when it caps, the character gain a curse with one of their traits. For example, the first enemy in the game is a cat girl, if she grabs you it will go for cunnilingus, and fill 1/3 or your corruption. If it caps you get cat ears, cap again, and you get a tail, again paws, and finally hypnotic beads, if you reach corruption again, it is game over.
Now the interesting part outside of the visual changes, is that your gameplay changes based on the corruption, rams are hypnotic orientated, cat girl movement orientated. Harpies flying, foxes summoning/ debuffing... So changing your gameplay and skills based on your corruption is a superb mechanic, because loosing is a punishment for the player, but you still could want to lose, different to most side scroller where loosing breaks the entire flow of the game.
Another thing, is how you deal with corruption. I pointed out before that if it caps at maximum is game over, so the game allows you to delete corruption by sacrificing crystals. Sure that is nice, nevertheless you could embrace corruption, and evolve the race and skills you are using. For example harpies, you could take your wings and talons off, but if instead you use plunge and egg attacks, it will fill a blue progress bar (different to the purple/pink corruption one). When filled, the character will go from a harpy to a dragon harpy, which increases damage, and massively increase egg explosion range.
So this constant duality of not wanting to lose, but wanting to gain some corruptions, and not reaching game over but wanting a class upgrade is fun. I think there is a nice balance between the options. And since I have not seen this type of gameplay before (maybe there is, just haven't seen it) it gains a lot of originality.
The gender swap turns me off a bit of thought (the mc is a man, reincarnated into a woman) but that is entirely personal opinion.
Overall I was just looking for a side scroller, but found an innovative game tha could become quite the masterpieces if is finished...(like I said I will not talk about development, but there's that)
So, for originality alone is above average(3 stars), and for an interesting integration of lewd things with gameplay, is 5 stars. Let's just hope it doesn't get abandoned and don't take 3 decades to be finished.
