Tetra (inspired by the fish neon tetra), is an entry for the Langjam gamejam.

Langjam Gamejam is a 7-day challenge to create a programming language and then use that language to build a game. You set the rules. Be as creative as possible, use any technologies you want, and have fun. There will be prizes for the most creative submissions!

Rules:

1. The hackathon runs for 7 days (starting on the 14th Decemeber 2025, at 04:59 UTC).
2. You must design and implement a programming language.
3. You must design and implement a game using your language.
4. You can use any language, engine, libraries, and technologies.
5. You define what a programming language is and what a game is.
6. Work solo or on a team.
7. Documentation and instructions are encouraged.
8. Bonus points: Write a blog post about your language, game, and design process.
