COPY THIS ↓

Use the uploaded gameplay video as the primary reference.

Rebuild the game shown in the video as a polished, fully playable browser game.

Do not just copy the visuals.

First, infer the hidden gameplay system behind the footage:
- player controls
- camera behavior
- movement rules
- interactions
- progression
- upgrades
- enemy behavior
- collisions
- scoring
- win and fail conditions
- UI feedback
- pacing

Reconstruct any rules that are not explicitly shown but must exist for the gameplay in the video to make sense.

Match the feel and structure of the reference as closely as possible while keeping the game stable, responsive, and actually fun to play.

Do not ask questions.
Make the necessary design decisions yourself.
Build the complete playable experience in one shot.
