Umbravore

You are a nameless shadow — and legends are edible. Six doors, six bosses, any order: win a duel and DEVOUR the boss whole. Its signature attack becomes your new button; its movement rewrites your dash (spider-walk trip-lines, quaking leaps, phase-dives, twin dashes). Kill order is your build: every legend is secretly weak to another's stolen power, and every devour makes the rest stronger. You can only carry THREE forms — and behind the seventh door waits THE WHOLE, a bone-white mirror assembled from everything you left behind. Roguelite boss-rush ARPG: no mobs, no grinding, pure duels. Hand-pulled silkscreen art, weekly time trials, an etching tree, and a chimera poster of every run. Others loot; you devour.

CARTOGRAPH

The dungeon does not exist until you draw it. You are a royal cartographer with a blank parchment, a few ghostly watermark rumors, and one bottle of ink — which is also your LIFE. Draw a corridor and paper walls fold up into a 3D pop-up world. Close a loop and a room grows inside: its prize is decided by how big and how TIDY you drew it. Enemies are ink blots that can only walk the lines you drew — so draw chokepoints, kite them onto a bridge, then switch to the eraser and drop the whole horde into the blank. Four atlas pages, four bosses that attack your authorship: one redacts your corridors, one plagiarizes your map, one eats your rooms, and the Blank King makes you draw the arena mid-fight while the page forgets itself. Every run ends by printing the ACTUAL map you drew as a wax-sealed poster — no two are alike. Daily survey: the whole world gets the same blank page; a thousand players, a thousand maps.

PLINKFALL

A physics pinball-descent roguelike inside a handcrafted wooden toy cabinet. You are a glass marble knight falling through the Toymaker's dungeon: every floor is a vertical pinball chamber with enemy tokens pinned among the pegs. Drag to aim — a physics-true dotted line previews your bounces — release, and momentum does the damage. Two flippers guard the drain, and every save is the wager that makes PLINKFALL sing: +1 RALLY and more damage, but every bounce charges the red hazard pegs until they go LIVE. Drain, survive the enemy turn, clear the chamber, then fit your build: bomb pegs, multiball splitters, brass crit chimes, lightning conductors, magnet marbles and twelve run-warping relics. Three acts end in articulated automaton bosses — one TILTS the cabinet mid-rally, one ROTATES the pegfield, and the Toymaker REBUILDS the chamber as you fight. Five hearts, permadeath, Daily Drop seed. Bright, bloomless, carved like a real artisan toy.

Lockstep

A quick TIMING PUZZLE rendered as a luminous brass orrery in true 3D. Concentric rings spin at different speeds, each carrying a glowing gem. TAP (or Space / touch) to lock the active ring the instant its gem sweeps through the gate at the top — nail the dead-centre for a PERFECT and grow your combo. Lock every ring to fire the beam and advance; each level adds rings, speeds them up, and tightens the window. Three lives, one button, escalating precision. Cinematic bloom, a reactive clockwork synth score, and a high-score leaderboard. Mobile-first, one finger. Tip: watch the gate — it pulses brighter as the gem approaches, so play it by feel.
