Speaking from my own internship experience:

1. The type of project you're doing: If you're applying to a game company, then your projects better be about AI, particle effects, or gameplay related

Bonus points if what you are doing fits the job description (in terms of the language you use or what your project is about)

2. Good coding practices (formatting, documentation, readability): Nobody wants to work with a guy who writes unreadable code
