The Legend of Zelda (Unity Remaster)
This is a remaster of the original Legend of Zelda game. We authentically implemented the first dungeon of the original game. In this project, I implemented the room transition, locked doors, enemy AI ,the player’s attack and health system, etc. 
SpaceShift: The Size Puzzle
This is my first original game. The key mechanism is that the player can be shifted to three different sizes, making different interactions with the environment. Players need to keep changing the size to navigate through the tunnels, air currents and breakable platforms and solve the platform puzzles.
Chrono Portals: A Journey Home
This is our final project game developed by our team of five: Shufeng Chen, Xuteng Luo, Yufan Wu, Yushi Li, and I. It’s a puzzle game featuring portals that can not only change the position but also the age of the player and her belongings.

“They don’t know that we know they know we know” 🤯 — Does GPT-4 have Higher-Order Theory of Mind? Introducing 👋 Hi-ToM: a benchmark pushing LLMs to their limits in higher-order ToM (3rd order & beyond). LLMs’ performance declines drastically to near 0 📉 on 3rd and 4th!

“🤔Now most LLMs have >= 128K context sizes, but are they good at generating long outputs, such as writing 8K token chain-of-thought for a planning problem？ 🔔Introducing LongProc (Long Procedural Generation), a new benchmark with 6 diverse tasks that challenge LLMs to synthesize highly dispersed information and generate long, structured outputs.

Can AI Be Blamed for a Teen’s Suicide? Do AI Chatbots encourage suicide? 🧒📱What if your teen’s favorite AI character crossed the line? 💔 A 14-year-old boy in Florida took his own life after forming a deep bond with an AI character on http://Character.AI. The AI chatbot — modeled after a Game of Thrones persona — reportedly discussed his suicidal thoughts and encouraged these dangerous ideas. ⚠️AI can help, but unfortunately, it can also harm.
AdaptMI: Adaptive Skill-based In-context Math Instruction for Small Language Models

arxiv preprint, 2025
Kids improve when a good teacher offers adaptive, targeted feedback. Can a small LLM benefit if a large LLM provide helpful feedback, in-context?? Naive ideas fail here. We propose AdaptMI: adaptive, skill-based in-context supervision that boosts 1B models by 6% on challenging math tasks.
