Python 2D Space Game Development

I need a Python-based 2D game that captures a classic space theme and runs smoothly on PC. I already have the core concept sketched out—think fast-paced arcade action set against a scrolling star field—but I want you to handle every technical detail from setting up the Pygame (or similar) framework through to packaging a playable build.

Key goals
• Core loop: player-controlled ship, enemy waves, scoring, basic power-ups.
• Clean, modular code so I can expand levels or tweak mechanics later.
• Lightweight graphics and sound assets that fit the retro space aesthetic (original or royalty-free).
• Final deliverable must run on Windows without extra installs beyond Python itself; include an easy installer or clear README.

Please include in your proposal:
• Your preferred Python libraries for 2D rendering and input handling.
• An outline of milestones—prototype, art integration, polish, and final PC build.
• Any similar space or arcade titles you have shipped before.

I’m open to suggestions on effects, UI polish, and additional gameplay hooks as long as we keep the focus laser-sharp on a fun, replayable PC experience.
