Project Description

This is like a world simulation game. Every character's personality is cloned from a twitter profile, Every character has a web3 wallet and have tools they can use, like calling APIs to create images, send money to others, mint NFTs and lots of other types of actions. I used this project to experiment with prompts, storytelling, API integrations, memory management, data visualizations, micro-animations, testing how good AI is at making humor... I learned how to use permit() so there's a government account that covers the gas for all the citizens in the game, I'm not sure if i'll launch on mainnet. Maybe i need more feedback first. I'm really thankful for this week because i had lots of fun building this, and made some friends on Discord too. Please if you check it let me know what you think!!
