Compare Shift Quantum prices across trusted key stores and find the best deal. Developed by Fishing Cactus. Published by Fishing Cactus. Released on 5/29/2018. Available on PC. Genres: Action, Adventure, Indie.

A spatial-puzzle platformer where you invert gravity and flip the entire level geometry to navigate through impossible spaces. Hypnotic and brain-melting in the best way.

I spent the first hour of Shift Quantum genuinely disoriented in a way games rarely achieve. The core mechanic is deceptively simple: press a button and the level inverts around you, flipping gravity, inverting platforms, turning walls into walkable surfaces. It sounds abstract until you're staring at a space that looks unsolvable until you realize you need to stand on the ceiling instead. The level design is tight and intentional. Each puzzle teaches you something new about spatial reasoning without tutorials or hand-holding. The pixel art is clean, the soundtrack is minimal and hypnotic, and the pacing respects your need to think. It's short (maybe 4-5 hours main campaign) but the built-in level editor and the ability to share creations extends the life significantly. If you enjoy puzzle-platformers that reward pattern recognition over reflexes, this quiet little game has something special waiting. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
