Shadowcurse is a free online 2D pixel platformer adventure where you control a lone wanderer fighting through a broken, shadow-consumed world. Armed with a blade and sheer will, you battle through dark, horror-tinged environments packed with enemies, platforming challenges, and story-driven quests that test how far you'll go before the darkness wins. No download, no sign-up – just jump straight in and start fighting.

The game blends tight platformer combat with an apocalyptic atmosphere, featuring beautifully crafted pixel art from a collaborative team of artists and a moody original soundtrack that keeps the tension real. Each area feels distinct – expect blood, shadows, and the occasional grim surprise. Combat is straightforward but satisfying, rewarding players who learn enemy patterns and push forward rather than play it safe. The quest structure gives you clear goals without hand-holding you through every step.

Shadowcurse hits the sweet spot for fans of single-player pixel platformers, 2D action-adventure games, and anyone who loves horror-flavored side-scrollers with some soul behind them. If you enjoy games like dead platformers with dark worlds, gothic adventure quests, or cute-meets-creepy pixel aesthetics, this one belongs on your list.
