About Osteoblasts
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
