I got this game on Steam because it was free and the description sounded like this was more than just a simple hentai game, and I was right. You're doing an awesome job, and I'm even more impressed to now know that this is a personal project. It already looks much more polished than most early access games out right now, so if this is alpha, I can't wait to see where this goes. As this is actually the first hentai game I've ever installed, ever, literally, I don't have much to compare it to in that respect, but I think your animations and character models are great and spot on. I do have a few suggestions, and I hope this is the right place to post them. If not, let me know where.
The only real suggestions I have for the graphics and animation, which are amazing already, is more variation in genitalia, both male and female, and some animation on the male side. To expand, variations on labia and clits at the very least would be awesome, as well as variation for penis and testicle size for males. Regarding the males, the stick straight permaboners are a little weird, and an alternate animation for a flaccid penis when they're just running around in idle mode (go erect for chase mode) would not only add a little more realism, but I think a LOT of humor. ;D
I also saw a couple previous comments referring to the lack of M/M sex in the game, and as a hetero cis male, I kinda agree that it should be included, even with the extra workload of creating a few more animations and the fact that a m/m copulation won't result in breeding, this game is far too awesome and polished to leave our gay brothers out of the fun. They can still breed their Nephelym with each other, and engage their own avatar only with partners of their choosing. This game has the framework already to be all inclusive.
Regarding gameplay and mechanics, I know it's still alpha, so these could be down the road already...
A minimap or even a menu map would be a BIG help for getting around, as well as waypoint markers on a compass hud. It is fun to just explore, but sometimes you get turned around and run in circles looking for the way to get somewhere.
Some of the Pussy Portals are kinda far away from convenient places, and I'm mostly talking about the one at the Homestead. It would be so much better closer to the main house so you can sleep quicker and not have to run all the way across the field when you're grinding (lol, pun intended) for Nephelym.
The only other suggestion I have so far is a help/reference menu. It's not really clear so far as to what the breeding mechanics are so I'm having a hard time figuring out how to fulfill the breeding requests because I don't really know how to do what they're asking for, or sometimes even what they're asking for in the first place.
Again, I understand this is still in alpha, so some of these things may be in the chute already. Just wanted to give some constructive feedback for improvement and let you know you're doing an AWESOME job on this project. For my first hentai game, I'm impressed. Keep up the great work. ;D
