About THE MULLER-POWELL PRINCIPLE



It is a sci-fi story that takes place in the near future. You are Harry Herman, an employee of Delta Laboratories who researches interdimensional traveling. You had been participating in a project that was supposed to benefit all humanity, but something went wrong. Through the gameplay, you will solve various physics-based puzzles using an energy-manipulating weapon, travel across space and time to explore surrealistic universes and find out the dark truth about this project and your connection to it.
Solve various puzzles and trick enemies using physics interactions and your special tool - the Portable Energy Manipulator.

PHYSICS PUZZLES & INTERACTIVE ENVIRONMENT

Many objects in the game can be picked up, brought somewhere, or manipulated in other ways. Whether it's a computer terminal, a box you can carry, or a simple mug on a table. Explore various interactive environments to find clues and return to the riddle with a solution, which in some cases may be several. Nothing was made for you to solve, there's no cube dispenser or an obvious exit door at the end. It's all for you to figure out.

PORTABLE ENERGY MANIPULATOR

The device you carry throughout the game can absorb different energy types from the environment and use them to perform various tasks.

Absorbing energy from a particular source will give the gun its’ properties. The heat energy from fire and radiators will melt glass, security cameras can be blinded by a beam of light, and for powering generators, you can take hazardous radiation from toxic puddles scattered across Delta Labs facilities. And of course, you will make an encounter with the quantum entanglement energy - the mysterious power capable of opening rifts between worlds.

Apart from solving environmental puzzles, your device can also be used against various creatures you'll meet in parallel dimensions. Most of the time you can't defeat your enemies; instead, you can use the Manipulator to outsmart or suspend them. Some enemies can be frozen in place using the force field energy, while others are sensitive to light and can be distracted by shooting a beam at it in the distance. You will require more advanced strategies and combining various energy types to pass them.

You find yourself in one of Delta Labs' off-world research facilities in an unknown dimension that looks more like a crashing-down laboratory. Your old friends Eugene and Alex try to connect with you shortly, and with their help, you start a journey through various dimensions. You will learn different physics interactions and meet unusual creatures on your way home. Along this, you have to unveil the mysteries of this project and your past.

Experience a non-linear story where your choice always matters. Can you get to the bottom of this, or just try to escape? Who to listen? Who to trust? Which side will you take? And will you finally “break the Principle”? That depends entirely on you.

Make your way back to Earth through mysterious parallel dimensions littered with puzzles and secrets, uncover mysterious connections between the worlds you visit, and reveal the dark truth about Delta Labs and your involvement with them. Dare to explore?

  • Solve various physics-based puzzles
  • Unique gameplay mechanics that involve an energy-manipulating weapon
  • A mix of sci-fi with surreal and esoteric themes makes the game setting a unique design. Most of the time you'll spend in bizarre alien dimensions
  • Deeply thought-out story and lore. Each location and each character in the game has its own story revealed through various notes, environmental narratives, and characters' conversations.
  • The game features multiple endings that can be achieved through different choices

Puzzles aren't puzzles when the only reason they're difficult is because you have to stop to run away from a mob until it despawns and then walk back to the 'puzzle'. The scripted chase sequences seem to have missed some QA because I soft-locked myself twice in two different areas and had to load to a previous save. Directions in some areas are unclear, to the point you wind up just button mashing whatever is available on the nearest computer screen until something dings. And while it might be of way less importance to some, in-game lore shouldn't need a science degree to be interesting. Nobody wants to scroll through dozens of pages of journal entries on quantum entanglement to find out what's going on in a game. 3 hours in and I was so bored sorting through word soup that I gave up bothering to know the story at all.

It's a decent puzzle-type game, but I did not expect nor appreciate all the horror sections that are just poorly implemented and rely on trial and error. Graphics are nice, music is alright. Puzzles are ok, most of them are kinda trivial, but there were places I got stumpted at for a bit. The story is.. there. Can't say I was overly interested, but it wasn't bad. Voice acting could've been a bit better, it did feel more like people acting rather than characters talking at times.

Played this years ago and completely forgot about it. Don't really remember anything about it so must not have been memorable. Though what i do remember is the dev stopping by and getting annoyed and treating me like an idiot because i was trying to solve a puzzle by breaking it. So yea not recommend.

I would give this game a mixed rating if I could. Its a neat concept and some of the puzzles are fun, but its most incredibly annoying to play.

Great story concept that starts getting "disentangled". The sci-fi premise and dimensional travel story are genuinely unique and interesting in the beginning then degrades and goes downhill. The Muller-Powell Principle COULD HAVE BEEN a fantastic sci-fi narrative game - But it wasn't. It sets up an intriguing, reality-bending world that immediately grabs your attention. Unfortunately, the writers committed a cardinal sin by having a major faction introduced at the beginning - never to be seen again until maybe you get the specific ending and then its only a mention. And also a cryptic character alluded to - then never mentioned again. There is also a huge plot hole as well. Adding insult to injury, the developers chose to bury that bad story under miles of artificial padding and some pretty bad mechanical coding. You aren't playing a clever puzzle simulator; you are actively wrestling with a broken physics engine. The gravity-tether mechanics are incredibly janky, dropping items constantly due to hyper-sensitive collision boundaries. Worse, the game's internal scripting frequently glitches out, forcing you to spend literal hours repeating things over and over and over again. …
