Thunder Barrage

Pilot a thunder fighter through storm airspace with auto-fire; downed enemies fill an energy gauge that space bar releases as a screen-clearing storm burst.

Start from this prompt

Fly an auto-firing thunder fighter through storm airspace, dodge high-contrast bullet patterns and break enemy craft; consecutive hits build combo and energy. A full gauge releases a screen-clearing storm burst, and losing all lives shows the score with an instant restart.

Challenge the three-phase storm boss

Turn the combat into a three-phase boss fight — cumulonimbus, storm eye and storm core — each phase with its own bullet trajectories, and allow retrying from the current boss after a defeat.

Build a browser bullet-hell shooter called “Thunder Barrage”. The player pilots a thunder fighter through steadily advancing storm airspace, moving and auto-firing, dodging dense bullet patterns and breaking enemy craft; defeated enemies grant score and energy, a full energy gauge releases a screen-clearing storm burst, and running out of lives shows the round's score with an instant restart. On desktop, move with the arrow keys or WASD and release the storm burst with the space bar; on mobile, provide finger-following drag controls and a prominent skill button. The interface keeps lives, score, energy gauge, combo and stage progress on screen, reinforced by hit flashes, impact effects, shake-like displacement and short sound cues.Visuals use deep-blue thunderclouds, cyan-white arcs and high-contrast enemy bullets, with the fighter and hazards always clearly outlined; the canvas scales with the screen, the touch area avoids the top status bar, and small screens stay readable with no horizontal scrolling.
Add a graze-multiplier challenge

Add graze charging and a multiplier wager: flying close to bullets builds thunder energy and combo, taking a hit resets the multiplier, with a halo and tone cues marking dangerous distance.

Add a low-pressure assist mode

Add an anytime low-pressure mode that lowers bullet density and speed, provides three automatic shields and high-contrast outlines, and warns through both shape and color.
