Four single-file web games, one design DNA: seeded, readable, permanent-meta that widens what each run can find. The same philosophy as the RogueFoundry Minecraft modpack — freed from the launcher. Pick one and play.
Contract → seeded dungeon → 3 acts → boss → extract → invest your gems in the Sanctuary. Fog-of-war, 6 enemy types, piercing shots, loot showers.
▶ Dive arena survivorAim with the mouse, hold to fire. Survive the waves and choose 1-of-3 upgrades at each level-up. Embers and best wave persist.
▶ Ignite sokoban puzzlePush every crate onto its sigil pad to seal each vault. Fewer moves, more stars. Six hand-crafted vaults, undo + reset.
▶ Open the Vault arcade runnerCatch hex runes, dodge red shards, ride the combo. Speed ramps, best score remembers you.
▶ Drop In puzzle logicMerge runes into ever-larger glyphs. 2048 is the floor, mastery is the ceiling. New seed, new luck, endless calm.
▶ MergeEverything is a single self-contained HTML file — no login, no install, works offline. Control feedback · benchmark results · provenance live in the benchmark channel.
