@Replit Updated gameplay with voice over - final submission for week 1

#agent4contentchallenge @Replit

[karthikeyan @karthik_coder]

🚀 Week 1 @Replit Agent 4 Content Challenge: Building 'Prompt Pong' LIVE — a Pong game where YOU control the paddle by TYPING prompts to an AI in real-time.

E.g. 'go up fast' → zoom up!
Super meta: Using Agent 4 to build a game about prompting AI.

@Replit Game now actually ends at 5 points... but no restart 😅 Just fixed it!

Added "Game Over" screen + big "Restart" button. Click → new match, scores reset, no page refresh needed.

@Replit fixed the out of bounds issue

[karthikeyan @karthik_coder]

@Replit Make it fun and add debug logs for prompt parsing. Deploy preview ready.

[karthikeyan @karthik_coder]

@Replit like 'go up', 'down fast', 'center now', 'block hard', 'dodge left' — parse the text every second or on enter/submit and translate to paddle movement (velocity/position).
Basic physics: ball bounces off walls/paddles with angle change.
Game over at 5 points, reset button.

[karthikeyan @karthik_coder]

@Replit Starting prompt:

Build a browser-based Pong game using HTML5 Canvas and vanilla JavaScript.

Two paddles, ball, score display.
Right paddle: simple AI that tracks the ball.
Left paddle: controlled NOT by keys, but by a real-time text input box on screen. Player types prompts

@shayaan_azeem @cursor_ai i want in

[karthikeyan @karthik_coder]

@nayana_chax @innercircle_so not a startup per se, building a few things which actually helps the community.

This is the current one in progress. In process of getting approval from strava for more atheletes.

[karthikeyan @karthik_coder]

@BatsouElef too many ideas, too many things, 😩
