About This Game

You are Harry Herman, an employee of the scientific organization Delta Laboratories, which was engaged in studies of possible ways to travel through dimensions. You were a part of a project that was supposed to benefit all humanity, but something went very wrong.

Solve different puzzles and outsmart your enemies using physics interactions and your unique device - the Portable Energy Manipulator.


Have fun by studying physical interactions: numerous items within the game are capable of being seized, relocated, or manipulated in other ways. Whether it's a door you should go through, a box you can carry, a terminal you can use, or even a simple mug on a table. Investigate various interactive environments for clues, explore upcoming puzzles, and find solutions, which in some cases may be more than one.


The universal device you carry throughout the game can interact with different types of energy from the environment, store it, and release it as shown. You could clear your way, protect yourself from the enemies, or destroy anything in your way. Why not?

Absorb heat from fire and radiators to melt glass, blind security cameras with a beam of light, and freeze physical objects in place by draining force fields. In the upcoming full version of THE MULLER-POWELL PRINCIPLE you will be able to remove hazardous radiation from toxic puddles, use it to charge power generators, and even harvest quantum entanglement energy — the mysterious power capable of opening portals between worlds. Utilize your device to its fullest potential!

Apart from solving environmental puzzles, your device can also be used against various creatures you'll find in parallel dimensions. Most of the time you can't really defeat your enemies, instead you can use the Manipulator to outsmart or suspend them.

You find yourself in one of Delta Labs' off-world research facilities in an unknown dimension, so it looks more like a crashing-down laboratory. All you can remember are the words “The Muller-Powell Principle” stuck in your head. You need to figure out the meaning of these words, otherwise, you’re doomed. Your companions should try to connect with you shortly, and with their help, you start a journey through various dimensions and unveil the mysteries of this project and your past.

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 involvement with them.
