A Premium Tower Defense Game In

make a premium tower defense game in the style of steampunk with a true overhead orthographic board, compact HUD, long square-corner maze route with switchbacks and loop-like courtyards, narrow readable road, build-anywhere clear floor placement, small buildings and pipes as obstacles, brass cannon towers with visible upgrade transformations, layered clockwork enemies, sparks economy, and modern high fidelity art Pixels 3.0 app-mode brief: Visual style/theme: steampunk with a true overhead orthograph. Use modern high-fidelity canvas art, not default pixel/retro graphics unless explicitly requested. Blueprint: premium lane-defense app with a winding generated route, defender pads, target entry/exit, leaks, sparks economy, rounds, and upgrade timing. Controls: click/tap pads to place defenders, click defenders to upgrade, R to restart, and a New Map control to reroll the route. Core loop: stop layered targets traveling the route, earn sparks, place different defenders, upgrade them, and survive every round. Required defender roles: fast striker, burst/splash specialist, and slow/control specialist. Each upgrade must visibly rework the unit art, projectile, range, and attack feel. Required targets: fast scouts, armored/layered targets, and split or shielded targets with different silhouettes and pop feedback. Map variety: use a non-straight runtime route with bends, switchbacks, loops, bridges, landmarks, and theme-specific props. Fidelity bar: memorable silhouettes, themed UI cards/icons, parallax/depth, shadows/glow, particles, distinct sounds, readable animation states, and title thumbnail framing that sells the theme. Prompt fantasy rule: important nouns and style words must become visible gameplay elements, not just title/HUD labels. Brand safety: use original names, art, UI, and assets. Do not copy proprietary characters, names, icons, maps, or exact commercial UI.
