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 that highlights valid zones after selecting a tower, visible no-build obstacles only inside marked decoration zones, 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.
