Love the concept! So few evil male characters out there you can play as that aren't little goblins. My key hopes/suggestions would be:
1: Focus on smoother/more realistic animations! I appreciate you're trying to throw out lots and lots of features, chambers, devices, etc, but in my humble opinion you'd be best served by hyper focusing on the key feature first - banging hot elves! As it stands, your animations have that VERY early Skyrim sex mod vibe like 'Animated Prostitution.' Games like MudBlood are VERY weak on roleplay, options, construction, etc, but the sex anims are smooth af and they're reaking in the patreon money for a reason.
2: Enhancing the NPC capture process. Another great game i'd hope you could take inspiration from is Goblin Walker. Replacing the elves that are just chilling at the front gates with villages, towns, farms, and castles for you to raid (making your game an effective combo of Goblin Walker and Mud Blood (with a dash of Mad Island), giving us the best of these games) that have randomly generated NPCs for you to hunt, and male civilians and soldiers who actively try to stop you from carrying your prey back to your lair, would add a TON of fun to the capture part of the game.
3. Character Customization/Options. The option to be the big orc, demon, human, dragonborne, etc would be chef's kiss. Making horns, bigger or different styles of wings, clothing, armor, accessories things you can unlock of find in the world would be awesome.
Thank you for the hard work! Look forward to your next update!
