Steredenn: Binary Stars

Steredenn: Binary Stars is a side-scrolling shoot-'em-up with roguelike structure—each run randomizes weapons, power-ups, and enemy patterns. You pilot a lone ship against waves of hostiles and oversized bosses, collecting gear drops mid-flight to adapt your loadout on the fly. Runs end in permadeath, but unlocks carry between attempts. The pixel-art style leans chunky and high-contrast. You can tackle it solo or bring a second player locally for co-op. Boss fights anchor each stage, demanding pattern recognition and quick repositioning. Weapon variety ranges from standard blasters to experimental tech, though the source doesn't specify exact types. It's built for short, repeatable sessions where mastery comes from learning enemy tells and optimizing gear synergies.
