Version: ??
Public Demo Release
Gameplay
You mostly just walk around, triggers scenes, sit through conversations and watch cutscenes, but that's all you need for this genre. It is a lot of reading, so don't come expecting instant gratification. An improvement over the second game is the mission system that serves to guide you along quest steps, but you are still rewarded for exploring on your own.
Visuals
Better than its predecessor in every way, so far. The characters full body designs are noticibly improved, as are the faces, the actual pixel animinations and even the environment textures. The town you play in looks great!
Audio
Likewise, the music is great and the game retains and improves all those 'extra' audio sources to spice up scenes both hidden and visible. The clapping of flesh behind windows or doors, the creaking of beds, the breathy moans... it's all back, and sound better than before.
Story
As this is only the demo version, obviously not too much has been revealed. But similar to HC2, there's a fairly long introduction period to properly introduce you to the main character and demonstrates the start and development of your relationships with the main girls. It is worth absorbing though, because it'll give weight and importance to the back half of the game. This is not going to be a quick blast through.
Lewds
HC 2 was great at slow burn corruption and I can already tell HC3 is going to set an even higher standard on that front. The main girls are clearly going to go through a long and drawn out corruption process, but the dev has also made sure to intersperse faster paced stories throughout even the demo to keep the players interested. I wasn't sure how this was going to be used, but so far I can say it's great. I don't think I've seen a single lewd scene from the main girls yet, but have already seen a few regular girls reduced to somebody's cocksleeve.
Additionally, HC3 makes great use of silohuettes, to show you things without fully showing you things. I can't wait to see that used more as all the girls both main and side get drawn into their downfalls. I hope to see a lot more 'little clues' alluding to secret relations, like splashes of cum or spent, tossed condoms; tiny sprites that could be overlooked.
Overall, a very promising start and I can't wait for more content. But I'll end on this warning for newer players to the series; this is a very slow-paced, reading-intensive, story-heavy game. Yes, you get to see side-girls go through quick downfalls, but generally you shouldn't play this if you're expecting quick pay offs.
