A physics-first metroidvania that will humble you, then addict you, Fern's elastic grapple hook is unlike anything else in the genre right now.

My first hour with Rusted Moss felt like the game was actively laughing at me. I kept plummeting into the same pit, convinced I was missing an upgrade that would explain why the traversal felt so alien. The truth is there is no secret upgrade to wait for: the grapple hook is the whole game, and learning it is the game. Once that clicked, I did not want to put it down. To understand what makes this worth your time, you have to accept that the grapple does not work the way any other game has trained you. Your companion Puck transforms into an elastic rope that latches onto mossy surfaces, and your movement is entirely governed by real physics momentum. There is no double jump, no dash, no safety net beyond your own read of the swing arc. The start angle of a latch point determines where you land just as much as the release timing, and the game knows this, so it builds its map around demanding you internalize that. Weapon pickups like the shotgun, sniper, and rocket launcher sit alongside the traversal but mostly serve the traversal: close-range shotgun blasts mid-swing to reposition, or a charged sniper shot to chip a witch while hanging from a ceiling bungee. Boss arenas are designed as movement problems first and damage checks second, which keeps the gun combat from feeling thin even when the weapon variety plateaus. The atmosphere is where the handcraft of a small three-person team becomes impossible to ignore. The pixel art carries a crunchy, melancholic weight in every biome, from the flat industrial decay of the starting flatlands to the genuinely striking mountainside zones. The soundtrack has that particular quality indie games rarely nail: it sits inside the mood rather than decorating over the top of it, something between desolate and quietly strange. The story draws on English and Nordic folklore, casting you as Fern, a changeling working to return the Fae to a world humanity is desperately trying to hold onto. Multiple endings and a branching implication give the lore texture without demanding you engage deeply if you would rather just swing around. None of that hides the friction. Some dedicated platforming corridors push the physics into territory that feels more chaotic than intentional, and a vocal portion of the community found the experience frustrating enough to walk away near the end. The good news is the developers built in a thorough Flexible difficulty mode with adaptive scaling, a game speed slider, and even a full flight mode that removes the grapple burden entirely if you just want to see the world. A Steam Workshop level editor ships in the box, and free post-launch DLC added over ten hours of additional content plus two new playable characters, which is a rare generosity for this price tier. Speedrunners found a thriving home here too, and the developers quietly blessed an unintended movement tech during QA because it was too good not to keep. Rusted Moss is built for people willing to feel clumsy before they feel powerful. If the physics-grapple concept sounds immediately exhausting rather than intriguing, the accessibility settings exist for a reason and deserve to be used without shame. But if you are the kind of player who replays a traversal room just to see if you can do it cleaner, this is going to feel like something made specifically for you. 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.
