Sometimes it’s hard to put into words what attracts us to a game. For instance, when I was asked if I wanted to do this Angel Engine review, I jumped at it like a shot based entirely on a two-sentence description and a single screenshot. While this approach has steered me wrong before, this time I found myself elbow deep inside the guts of an indescribable creature that is somehow called an Angel…so, it worked out fantastically.
AUTHOR'S NOTE: This game was reviewed before the writer was made aware of the original 'Angel Engine' webseries, and as such, this review has been based entirely on the contents of the game with no outside media influence.
What Is Angel Engine?
Angel Engine is a first-person horror puzzle game that tasks you with operating on various bodies that are suffering from “defects”. Using your sophisticated and grimy equipment, you must operate on the bodies to ‘perfect’ them before moving onto another. As you go, you’ll have to swap between equipment on the fly, keep everything from overheating, and prevent your subject from waking up to exact their revenge on you.
Mostly, it’s a game about juggling various needs without letting any of them get the better of you. It, weirdly, puts me in mind of “Papers, Please”, though in this, instance the consequences for failure isn’t that your wife and children slowly starve to death, it’s that you’re eaten alive by a horrific monster…sure, it’s more on-the-nose, but you can’t fault the game for its logical brevity.
Gameplay Is Far More Important
When it comes down to gameplay, things are a cross between Trauma Centre and WarioWare, with Angel Engine basically functioning as a collection of mini-games strung together by horror, grime, and invasive medical procedures. You access the desktop PC in your office to send in the next bunch of bodies to operate on, then you have to use the mechanical arm on your desk to find the wounds that cover your subjects’ bodies. Next, you use the ‘tool switcher’ to pick which tool you need for any given job.
It starts out with just needing to keep your equipment from overheating or your patient from waking up, but as you go, more complexity is added. A few operations in, and you’ll have to stop things every so often to replace fuses or restore power to your workstation before something catastrophic happens. Not only does this ramping up give the game a decent difficulty curve, but it certainly helps the tension to ramp up as well, and by the end, you’ll feel like a crackhead with the jitters the game has given you.
High Stress, High Reward
One of the things that attracts me to Angel Engine, outside of it being an indie horror game, is the storyline. As the game starts, you’re presented with an ominous introductory message that gives hints into the backstory of the world and what’s going on, but you’re not furnished with anything too overt. As you poke through the different user areas on the PC and talk to the night security guard, you slowly figure out what’s going on, piecing together the tiny bits of information you’ve been able to glean.
In many ways, it’s a method of storytelling more familiar in ARGs and indie horror webseries. You’re presented with a specific world-state but not with much information about the world or how it got to where it is, and the draw is figuring out the mystery as you go. How much you’ll figure out depends on how much you enjoy theorising, and there’s more than a hint of the “story designed for YouTube theorists” vibe to the game, but if you’re into the style, it’s enjoyably handled.
Graphical Style
Angel Engine is far from being high-end. Even my 2017 gaming laptop managed to run the game without chugging, so as long as you’ve updated your PC in the last decade, then you’ll probably run it just fine. The style is similar to Dread X Collection 3 with a definite ‘old school’ vibe supplemented with various screen filters. It’s a good aesthetic for the game and conveys everything necessary to understand and play it, but it’s also not going to be setting the horror world alight with the graphic design.
Music is a similar story, though the use of sound effects is pretty top-notch. Pretty much everything has an aural indicator of what is happening and what you’ll need to immediately deal with, and much like noises in certain horror games, by the end of your session, these indicators will send you into a fit of panic. Truly, if you can say anything at all about Angel Engine, it’s a game that thrives thanks to its excellent sound design.
Short, Sweet, but Occasionally Frustrating
All-in-all, the gameplay in Angel Engine does a decent job. There’s enough variety to the mini-games and enough of a curve in terms of what you’re expected to do that it never feels overly demanding or challenging, though it certainly feels tense enough. Part of the reason this balance works so well is due to the game’s relatively short length of only a few hours. However, your mileage may vary depending on how much you enjoy the individual mini-games themselves.
A couple of the mini-games are basically variants of Flappy Bird with extra bits thrown in, and trying to complete these while under pressure is both challenging and frustrating in equal measure. Before long, I started to dread these mini-games when they came up, though I often completed them just fine as long as the world wasn’t collapsing around me. Just watch out for the overheating because it has a way of sneaking up on you once the game has piled on fuse-breaking and electrical failures.
Final Word
Angel Engine is a great, short horror title that pushes your ability to multi-task to the brink while you’re already on edge for the inevitable jump scare. While the graphics are both low-end and relatively routine, the excellent background story elements and sound design go a long way towards righting the ship, and outside of minor mini-game frustrations, this is a worthwhile experience for any horror aficionado.
