I've been following DSD for a while, so I know that they can be extremely brilliant at times, and very disappointing at others.
First of all, The mortuary assistant is great. Wonderful. it gives you exactly everything it promises in a very tight package, it looks great, it sounds great, and with many moments that are truly blood-chilling. HOWEVER. The awe factor quickly runs out as soon as you figure out that there's no threat, there's no variety, and there's really no story either.
In order. This game is made by (mostly) a single dev, which is fenomenal, because the animations are rough but smooth and believable, the characters look like people (which in the game of the psx-horror obsession, it means a lot), the maps are very well done in terms of size, detail and usage. Everything in the game has a purpose, there's even a purpose for the weird matches that are the only thing you can take in the entrance. As for the game, it's exactly like in the title: you're a mortuary assistant, and wheter or not the tasks you're doing are realistic or not, they FEEL authentic, which is very important.
Now, the corpse routine is exactly the same for every single body, and there's always three bodies every night, with no variation and no increasing difficulty. And even though the bodies are randomly chosen, there's only like five possible ones, so you'll see the same faces a lot, considering there's five endings. That means at the very least, to see everything the game has to offer, you'll have to go through 15 bodies, out of the 5 available.
The scares and events are also random, which is good, but for at least 5 runs, there's not nearly enough of them. I've actually gone through the same scripted sequence three times in three consecutive runs, and there's no skipping these. You're forced to stop and do them all. On that note, you're not allowed to change the corpse task order either, you have to do number 1 before number 2, even if nothing should be stopping you, and if you start a corpse you have to do the entire procedure, you're not allowed to stop and put it away no matter what.
The key here is repetition. There's not enough variety for what the game wants to be, and there's not enough player freedom to be able to circumvent this problem. You're forced to do the same sequence and see the same things over and over for... not a whole lot. The story is basically all in the intro cutscene, and one or two endings. Even then, those two endings only give you a bit more context to stuff you can very well piece together from environmental clues, and the other endings are just slight variations. You even get the same burning cutscene wheter you chose the right body or not. That just makes no sense.
End of the day, it's a great game, really fenomenal. But for the price it has, I just wish it offered more than 3/4 hours-ish of stuff, of which, really just about an hour is interesting, and the rest is repetition. Much like me writing repetition so many times in this review.
It works great, but you could do better.
