I've gotten most of the endings except for A (I will cover later why I ended up giving up on this ending), along with trying to be thorough in my playthrough and, I gotta say, compared to their other games, Decaying Delicacy is just kind of disappointing. To be clear, there is a lot of potential here, story wise and with the zany elements, but the gameplay and presentation of the story left a lot to be desired.
First off, I think it's important to future buyers to be perfectly clear about the gameplay loop. For the majority, if not almost all, of the runtime, you are basically going to be running through mazes, trying not to be caught by monsters, each iteration becoming more difficult with unique challenges such as enemies only becoming visible at certain times, movable objects, increased enemies, and sound cues. The concept is cool in theory, yet dull in practice, as this means Decaying Delicacy lacks the interesting environments, characters, horror, and opportunities for story that their other games have.
Moreover, the maze is extremely unforgiving, and, if you bump into an enemy even once, rather than being able to try again, you're sent down the path of an ending. I gave Red Haze a hard time, but, at least that game restarted by default and did give you options to continue on and try again. If going through all of that to unlock some snippets of text for an admittedly intriguing story sounds interesting or fun to you, hey, this might actually be the little experience for you.
Secondly, since I brought it up earlier, it's time to finally address it; the story. It's not a bad one. I think its attempts to cover the idea of dreams vs reality and how the traumas of our life can come back to haunt us even in dreams is a really interesting one. That being said, this game mostly tells you everything about the story rather than showing. This is because, as I said, most of the story is conveyed through the main character talking to herself through text. After you complete each maze, you are given snippets of text that further explains the situation and how she's feeling/suffering currently. So, while the idea at their core is good, the presentation was boring and unfulfilling to me, as I felt I was being given scraps of an idea, but never stepping close to the fuller picture.
I've gotten all the endings except for one, and while I found the basic idea around each interesting, along with having potential, the way they were presented feels more flashy than actually being productive. I could tell you visually what I saw and some vague inferences from each, but nothing that would take me closer to actually understanding what the story was trying to convey. At each of the endings, I felt how I do at the [i]beginning[/i] of most Yai Gameworks titles, which really isn't a good sign.
In short, the idea is good, I think some refinement of its elements could work well in a longer, more story based game...albeit with more to do besides mazes. The end result however feels hollow. All That being said, out of all the Yai Gameworks titles I have played, this is the weakest in my opinion. It lacks what their better titles have, and is just an hour or so long of the worst parts of My Hole Is a Mouth of Dirt. An interesting idea suffered by being forced into such a short experience, and, besides three moments [spoiler]the sleeping or dead test, the bad ending, and level 9[/spoiler] nothing truly unnerved or scared me in this title.
That being said, this definitely isn't the title to judge the creator on, and I assure you they have much better titles, including ones you can support them through (or free ones you can buy the soundtrack through to support them). Close Your Eyes (great starting point and probably the most popular for a reason), Feast Your Eyes, My Hole Is a Mouth of Dirt, and Take The Dream IX are just a few that come to mind. I'd say explore those titles and skip this one unless you're curious, since it's cheap.
