The fights were fun and the story was definitely interesting. It lacked a bit in the "prey and predator dynamic" for yourself. As Eden turns from sexual prey to sexual predator there is not much preying on others. I was thinking in every fight that instead of actually fighting I would like to just pounce or be pounced, turning it more into a kind of battle-fuck game.

I know this is not the direction the game is moving toward and understand that even for this little story, the amount of work to create something like that would be way too much work in terms of animation.

Then again:
-> The fights were fun and figuring out how to win was definitely interesting.
-> The demo was really linear so it wasn't hard to figure out what to do.
If the story and map becomes more open, it might turn into a tedious search to figure out how to beat the next opponent which might become annoying. Many love those kind of puzzle solving tho.
-> The fights contain almost no lewd interactions (That's why me and others were going after the pounce like madmen).
With the complex but fun battle mechanics you built it feels like adding more lewd ways to fight (fighting back with ejaculation or just straight up fucking for example) would mess with the whole system you made, which feels kinda like a waste as you are definitely skilled in design and animation. All the actual lewd interactions where a joy to see. Seeing more lewd animations is always my goal in lewd games. No matter win or lose.

-> The designs for Characters, the setting, the story and the interactions are really nice and I enjoyed the dialogues.
-> Probably because it is still a demo, the sudden jump from zombie apocalypse where everyone attacks everyone to a cozy festival where everyone is just chilling, including the zombies, felt very weird.

This change in setting would need to be built up slowly or not change at all. From my opinion it should either be apocalypse from beginning to near the end or change almost immediately at the beginning of the story as some sort of prank.

-> Story-wise it was quite interesting. Can't wait to figure out what these two weirdos which you freed were. It felt a bit rushed tho. Like you tried to force as much story into this demo as possible as it was needed to show the main character change. I'm already sure it will move slower as you progress so I'm not worried in that regard.

=> Overall I'm already hooked and will surely buy it if it comes out.
