Compare Osteoblasts prices across trusted key stores and find the best deal. Developed by Moonana. Published by Moonana. Released on 2/12/2021. Available on PC. Genres: Indie, RPG.

A handcrafted solo-dev dungeon crawler that earns genuine cult status with pixel artistry and a marrow-based combat system unlike anything else in the genre - if you're patient enough to crack its cryptic shell.

I have a soft spot for games that smell like a single person's obsession, and Osteoblasts has that scent all over it. It was built almost entirely by Anglerman, Moonana's animator, and that background shows in every frame - the pixel work is meticulous, the enemy designs are genuinely strange and funny, and the combat screen has this first-person dungeon-crawler silhouette that feels deliberately weird in the best possible way. The setup is wonderfully absurd: a Cat Witch resurrects your skeleton and points you at a world where dogs are the primary menace, waging war on catkind by stealing tomatoes and burying your bones back underground. You pick one of six classes - samurai, shaman, and others - each with its own quest lines threaded through the overworld. The class choice is more than cosmetic. Gear you find or buy modifies which skills are actually available to you, and the marrow system (the game's take on MP) means you're constantly deciding whether to attack now or recover resources for something bigger next turn. Manipulating your own stats to unlock gated abilities, or debuffing enemies to shut down their move sets, gives the combat a genuinely clever texture that rewards attention. Where the game stumbles is in communicating its own rules. The stat thresholds that unlock certain spells are never explained cleanly, and players who don't enjoy learning through failure will find the onboarding genuinely hostile. The story, meanwhile, leans hard into deliberate obscurity - characters wax philosophical about the nature of bones, the plot drifts into hazy territory, and multiple endings exist but the journey there doesn't build toward them with much narrative weight. A single run clocks somewhere around nine to twelve hours depending on how thoroughly you explore, and the randomized loot keeps early runs interesting, though the affix pool starts to repeat itself before the credits roll. What consistently earns goodwill is the audiovisual craft. Elektrobear's soundtrack plays through both exploration and combat with no jarring transition - mellow overworld themes score your fights until a boss theme arrives and genuinely lands. The background art in battle areas varies by location, giving swamps, deserts, and battlefields their own pixelized atmosphere. There are Metroidvania-adjacent exploration rewards too - hidden statues of gods offer passive bonuses and fast-travel points, and boss keys gate progress in ways that make the map feel like an actual place. Steam players have kept an 85% positive score over its lifetime, which is a quiet but telling signal for a game this small and this strange. Osteoblasts is for you if you can tolerate a game that trusts you to figure things out, rewards a patient build-crafting mindset, and doesn't need a tidy narrative bow. It is not for you if unclear mechanics make you close tabs. Kai, Scout Team

Best for patient dungeon-crawler fans who enjoy figuring out obtuse systems and don't need the story to hold their hand.

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.
