Voidline

A top-down space arena where your ship cannot shoot. Instead you fire a tether that latches onto floating debris, and then that debris is your weapon: swing it in an orbit to shred anything it touches, fling it as a projectile, or hold it between you and incoming fire as a shield. Your loadout is whatever the arena happens to be full of.

How it plays

• Speed matters more than size. Damage is mass times relative speed, so a fast-swung boulder one-shots almost anything and the same boulder drifting does nothing at all. Learning to be moving when you connect is the entire skill curve.
• Rocks break, and the pieces are still ammunition. Every hit chips the rock you hit with; when it goes, it shatters into two smaller ones that are immediately re-tetherable. A long fight grinds the arena down into gravel, and gravel hits like gravel.
• You can hold two at once, one on an inner orbit and one on an outer, in two different colours. Two rocks at two radii is the ceiling of what a person can read, and it is enough to keep one as a permanent blade and use the other as a throwing arm.
• The field thins as the waves escalate. Six drifters in a dense debris field, then seekers, then turrets that shoot slow aimed bolts you can block with a rock, then splitters that break into two more. By wave five there are fewer rocks and more of everything else, and that scarcity is the difficulty — nothing ever just gets more hit points.
• The boss is the exam. A core wearing six armour plates, and nothing in the game can hurt it except those plates: tether one, tear it off, and fly it into the thing it came from. Six times.

Everything on screen is a generated polygon drawn as additive line art on near-black, in one two-pass neon stroke — a bright core over a wide dim halo — with motion trails on the ship and everything it is swinging. There is no sprite, no font and no audio file anywhere in the build; the rocks, the letters and the sound are all generated at runtime. The arena wraps on both axes, so nothing ever stops.
