I know that this was an unrated jam. But I would still like to point out a couple submissions which I personally think turned out exceptionally well in certain regards. If your game is not mentioned here: Don't worry. It doesn't mean I didn't like it. Just that it didn't stand out for me in any particular regard. Also, this is just my personal opinion. Feel free to disagree.

Best Gameplay:

This one for me goes to Dating Joyce: a Deckbuilding Game by omshinwa18. NSFW games are usually infamous for gameplay that is either bad or non-existent. But this one is actually a pretty decent card game with gameplay that is a great metaphor for what happens in the narrative of the game.

Best Aesthetic:

This is for me a tie between two games:

Midnight Delight -Demo- by Kiga. Proving again that finding a good color palette and sticking to it is half the battle. The other in this case is some creepy surrealism.

and

Dimon - The Witch's Pervert Assistant by DimonFreelancer. Because of a super cool style combining pixel art with a bold comic strip look.

Best Character Design:

I will have to give that one to Spa 129 -DEMO- by Nekolag. I just love the creative character designs in this game. 

Best Audio:

Easily Doting Dominatrix by Depression Deity. I thought I didn't have a submissive bone in my body. But after hearing her sultry voice calling me a "good boy", I am not so sure anymore.

Best Writing:

Clearly The Demon, Lilith by inlustria. A wonderfully written interactive novel that kept me constantly engaged from start to finish.

Most WTF game:

We shouldn't forget that game jams are about throwing stuff at the wall and see what sticks. So we should be bold and try weird things and see where it leads us. For this jam, the game that epitomized this approach for me was Riding a Giant Rabbit through Six Degrees of Prototyping by Grave Reaper Cushions.
