I like the art, I liked the original setup. But more and more stuff is being added to bloat the vision. I fear this game will become a lot like others games where you practically need a guide to 'find' all the scenes. Coffee is the best example I can think of. Despite having sunk hours and trying to follow guides, I still haven't seen every scene in that game that the screenshots show. Research, colony management, a scene that can only be seen from going down a 'route'. These things may be a nothing burger; but I get the vibes that the game is getting bloated and losing it focus. It was presented as a 2D side scroller porn game with top notch animations.
In short I hope the dev doesn't fall in the same trap so many other games did by trying to add too much to the game and then bogging it all down to the point where anyone who didn't play it from day 1 practically needs a walk through. Or that entire patches added stuffs or is time spent fixing bugs to mechanics that aren't related to the actual core game play loop.
I think a better focus would be to expand upon the captured mechanic/breeding room. Few games have a "What happens after game over." and it could help this one stand out even more. ATM the breeding room is more or less just a second wind respawn point that generic for all the monsters.
Overall the animation and art style is what carries this one.
