Oh wow, it's your games are getting more ambitious with every jam at a really incredible pace! I love everything you've done with this entry! There's a broad cast of characters, secret stuff to find and even sex combat! I also liked how the ending ties directly into the prequel, that's a very cool detail.
The pixel art looks great, and there's a lot of it in this game! Love the variety of characters, they've all got their own body type and look to them. It's also neat to see them walking around the world now, the little map versions are cute. The combat has a cool retro look to it with the checkered background and unique images for every special move, it's also nice to see that the moves change based on the opponent you're facing.
There are only three potential areas of improvements I can think of. First, the combat sounds can be less "smash" and more "boing", you can even try moans, but those may end up sounding cheesy. Second, It may be better if the player recovers Endurance between encounters, instead of making bathroom trips, maybe the bathroom can only be used once and recovers your Stamina? And lastly, I didn't immediately recognize the crowd sprites as crowds, so maybe they can have a few extra bits of detail to them while still remaining indistinguishable?
Really fantastic work this year, I hope to see more of this world you're building!
