One-thumb touch controls, portrait and landscape, procedural neon art and audio, cloud-saved bests with a shared leaderboard.

Nova Lance
Nova Lance is a 3D on-rails space shooter that runs in the browser with no build step and no external libraries — a hand-written WebGL renderer draws the low-poly ships, the corridor of glowing speed-ring gates and every particle effect. You fly a lance-class interceptor down a neon corridor with auto-firing wingtip cannons, chaining combos through drone swarms, gunners, rocks and capital-ship boss fights, and charging a piercing LANCE beam you unleash with a tap. It opens on an autonomous attract demo and the first intentional tap launches a real run.

un mini undertale
HOLLOWHEART is a tiny Undertale-style soul duel: each turn pick FIGHT, ACT, ITEM or MERCY, then survive a short bullet-hell onslaught as a red SOUL trapped in a white box. Befriend all three monsters (a dust-moth, a cinder imp and a hooded warden) for a pacifist ending — or cut them down and live with it. One-thumb touch play, portrait and landscape, original pixel art and chiptune.

touhou 6: embodiment of scarlet devil (touhou da
An original vertical bullet-hell danmaku. Choose Rei the shrine maiden (homing spirit amulets) or Mari the night magician (piercing star laser), weave through hand-authored spell-card patterns, and defeat Carmilla the Scarlet Devil across five phases. Drag to move, focus to slow down, bomb to clear the screen. Fully playable in portrait and landscape with a self-playing attract demo.

VECTOR STORM
A vertical-scrolling arcade shoot-'em-up in the spirit of Raiden. Collect drifting power-up pods to switch and level up four primaries — Vulcan, Wide, Laser and homing Bend Plasma — plus standard and homing missiles, then survive escalating waves and multi-pattern dreadnought bosses. One-thumb drag or keyboard, portrait and landscape, with combo scoring, screen-clearing bombs and a saved best.

Hanabi Forge — Danmaku Level Maker
Hanabi Forge is a danmaku bullet-hell level maker: drop emitters on the field, sculpt their burst shape, motion and timing, and arrange them along a timeline — then hit Test fly and dodge your own creation. Ships with six pattern presets, a scrubbable barrage preview, JSON export/import, and a real survival run with grazing, scoring and best-score tracking.

Frostbloom Protocol
A Touhou-style danmaku boss rush: fly Daiyousei or Cirno against the ARACHNE-9 android across five escalating spell cards. Graze bullets to charge your power, thread a thousand projectiles, and capture every spell for the highest score — playable one-thumbed in portrait or landscape.
