Challenges I ran into

🐛 Main Challenges I Ran Into

1. Farcaster Integration Complexity

Problem: Implementing Farcaster Mini App from scratch to production manifest was extremely challenging.

Issues:

• Complex authentication flow with account association
• Manifest configuration with proper metadata
• Webhook setup and validation
• Frame integration and button actions

Solution: Built custom authentication middleware, configured proper farcaster.json manifest, and set up secure webhook endpoints.

2. Silent Score Submission Bug

Problem: Game scores weren't being submitted when players finished games. The function existed but never triggered on game over.

Solution: Replaced the entire scoring system with a custom function that only submits all-time high scores.
Here's a cleaned-up and more polished version of your entry with mention of Phaser and some technical flavor, while keeping it concise and professional:

3. Destructive Platform Logic

Problem: Destructive platforms were being destroyed the moment the player touched them, rather than after the player had jumped off — breaking intended gameplay mechanics.

Solution: Implemented a state flag to track when the player is standing on a destructive platform. Using Phaser’s collision system, destruction is now delayed until the player exits the platform. This required a more nuanced approach to collision callbacks and player state management within Phaser’s physics engine, but ensures consistent and fair gameplay.
