An origami-themed hack-and-slash with a clever dual-dimension gimmick that launched in Early Access back in 2017 and, as of this writing, never actually left it.

I respect a small team swinging for something ambitious, but my patience has limits, and Upside-Down Dimensions burned through most of mine before I could even form a rhythm. The core pitch is genuinely interesting: you alternate between two characters, Ryuu and Keiko, each locked in a parallel paper-craft world split across contrasting seasons. Ryuu handles the hack-and-slash side, chaining sword combos against waves of origami samurai and oni enemies drawn from Japanese mythology. Keiko's dimension is the quieter one, built around stealth and puzzle-solving, with box mechanics that connect both worlds as her primary tool. On paper (no pun intended), that split-role design should keep things varied. In practice, it depends entirely on whether the game is running cleanly on a given build, and that is not a bet you can reliably win. The art direction is the strongest argument for giving this one a look. Every object in the world, trees, rocks, enemies, even the water, is constructed from papercraft and origami geometry. The two dimensions are set in different seasons, spring versus autumn, summer versus winter, and as the story progresses the worlds begin to bleed together visually, burning at the edges as the Dark Shogun's influence grows. It is a genuinely attractive aesthetic, low-poly but deliberate, and the enemy designs especially carry real character. Ryuu's sword attacks shred foes into scraps of folded paper, which lands with a satisfying tactile quality that you do not often see at this budget level. Combat feels punchy when it connects, and the combo system has enough depth to keep the action side interesting across a few hours. Here is where I have to be straight with you though. This game entered Steam Early Access in August 2017 and the developer's last update on Steam is listed as over seven years ago. The Kickstarter campaign it ran during development fell well short of its funding goal. Early previews from around launch flagged game-breaking bugs, including crashes immediately after the intro cutscene, and persistent issues with the box-puzzle mechanics that even internal devlogs from 2017 acknowledged were causing inconsistent behavior. Performance was enough of a concern that the team wrote publicly about CPU and GPU optimization passes just to chase a stable framerate in Unity. The camera-flip transition between dimensions, a mechanic that is literally central to the whole experience, was still being reworked in late update patches. None of this signals a project that reached the finish line. The local co-op mode was added as a post-launch feature, which adds some couch appeal if you want to split Ryuu and Keiko's roles between two players. The RPG layer includes a life and mana bar system that scales with level, and the origami summoning mechanic, where you can transform enemies into origami creatures and call them into melee fights, shows real creativity. The soundtrack was purpose-built for the game and fits the aesthetic well. All of that counts. But a game that still carries an Early Access label eight-plus years after launch, with a single Steam review in its history and developer communication that went dark, is not a game you should buy expecting a finished, stable product.

GamerScout Verdict

Charming art and a creative dual-character concept trapped in an unfinished, long-dormant Early Access shell - approach with low expectations.

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.
