About

THE MULLER-POWELL PRINCIPLE is a sci-fi thriller taking place in the near future. You are Harry Herman, a scientist at Delta Laboratories, a research company that specializes in interdimensional travel. You had been participating in a project that was supposed to benefit all humanity, but something went terribly wrong. To uncover the secrets of Delta Labs and set things right, you'll have to make your way through odd and surrealistic worlds.

Solve various puzzles and trick enemies with your special tool - the Portable Energy Manipulator, a weapon designed to operate with various types of energy․
PHYSICS PUZZLES & INTERACTIVE ENVIRONMENT
In this game, the solutions to the puzzles aren't obvious. Sometimes all it takes is finding a generator and plugging it in to power up a room. However, in many cases, a more complex approach is needed. You'll be interacting with many objects, such as computer terminals to find clues, obstacles to remove, and boxes to carry. Even a simple mug may come in handy. Explore the environment to find the best of many possible solutions. Here, you won't find a cube dispenser or a highlighted exit door at the end. It's all on 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. Use heat from fire and radiators to melt glass, disable security cameras with a beam of light, and take hazardous radiation from toxic puddles scattered across Delta facilities. Eventually, you'll encounter quantum entanglement energy sources - the mysterious power capable of opening rifts between worlds.
Strange and dangerous creatures inhabit parallel universes. Most of the time, you can't defeat your enemies. But the Manipulator may help you to outsmart and bypass them. Some enemies can be frozen in place using the force field energy, while others are sensitive to light, so you'll have to blind them. The further you advance, the more thinking it will take to find your way out of another trap.

You find yourself alone in one of Delta Labs' off-world research facilities in an unknown dimension. Everything around here looks as if it's about to fall apart. As you find a radio transmitter, some people will contact you. It looks like they’re old acquaintances: Eugene and Alex, and it seems they want to help you find your way back. Here’s the thing: one of them is very friendly, while the other clearly thinks you’ve made a huge mistake and blames you for it. But whose advice is better to follow on your journey through parallel universes and surreal worlds?
Experience a story where your choice really matters. Can you get to the bottom of this, or just try to escape? Who to listen to? Who to trust? Which side will you take? Will you finally break the Muller-Powell Principle? That depends entirely on you.

Make your way back to Earth through mysterious parallel dimensions littered with puzzles and secrets to discover, uncover mysterious connections between the worlds you visit and reveal the dark truth behind Delta Labs and your connection to them.

Reviews
Pros: • Generally good game with [b]Half-Life 1[/b] vibes. Although it reminds me [b]Soma[/b] and [b]Moons of Madness[/b] too. Cons: • Some game-breaking bugs • Some unnecessarily high difficulty peaks Summary: An OK game, but require some polishing. And TESTING.
dumb puzzles, dumb story, dumb philosophy or whatever it's trying to impart. it's deep if you whatever you slipped on in the parking lot is deep.
暴走事故により多元宇宙へと接続してしまった研究基地から脱出するパズルアドベンチャー。重力・光・炎・放射線・運動力など様々なエネルギ-を吸収し放出するデバイスを駆使し、複雑な研究所や異世界を探索する。 半透明の幽霊?が主人公を付け狙うが出現箇所はわずか。ジャンプスケアはなく死体や流血などホラー要素は弱め。戦闘はボス戦のみ、探索とパズルがメインとなる。 FPS視点の画面は高精細ではないが、無機質な研究所や奇妙な異世界や悪夢世界など背景はよく作り込まれている。薄暗い箇所は少なくて見やすく動作は軽め。 主人公の移動速度はそこそこ速いがダッシュはなし。ジャンプ力は低く異世界でのパルクールはやや苦労した。怪物は動きは遅いが倒すことはできず、狭く複雑な通路では自由に逃げることもできない。出現パターンは固定なので死に覚えで対処するしかない。恐怖感よりイライラが募る。 研究所などマップ構造はかなり複雑。デバイスでしか開けられない扉、ワープポータルや無限ループなどが多数あり、ルート探索がゲームの肝と言える。キーアイテムやエネルギーポイントなどを見落とししやすいので探索は慎重に。 セーブはチェックポイント式、こまめにセーブされるし過去の履歴からもロードできるので死にやすいがリトライは楽。マルチエンディングも周回プレイせずに見れる。 日本語訳はなし、英文テキスト量はかなり多め。重要なヒントが台詞や端末のメールログにかかれていたりするが読解は困難。私は早々にストーリーの理解を諦め、謎解きのいくつかは攻略サイトのお世話になった。クリアには9時間かかった。 ホラー要素は薄いがSF的な世界の作り込みは(インディーにしては)圧巻。難易度はやや高め、手応えのある探索を楽しみたい人におすすめ。
Красивые скрины, красивый трейлер, но играть в это.. скучно?
I like burning Kettles
Неплоха головоломка, жалко что короткая, а многие механики для загадок используются мало и не успевают раскрыться. Надеюсь, в следующем проекте будет более обильный продукт

las mecanicas son muy repetitivas y la mayoria son molestas, ademas del jodido fantasma que te persigue y te atrapa cuando se le da la gana, porque se le da la gana
Awesome
