Ok, #vibejam is over, and here's a video of my submission, Tron: Light Cycles. Built on @cursor_ai with @threejs. Play it here: tron.ganji.me
It was a fun experience overall and I learned a bunch of things. Thanks to @levelsio for organizing it.
Costs breakdown:
- @cursor_ai's $60 subscription and $30 extra usage. Tried to use it economically and default to composer 2, only switched to frontier models for complex problems.
- Used @ElevenLabs for the background music, got the creator subscription for $22 which was unnecessary, could've used the $5 account instead.
- @veedstudio account $30 for editing a social media video. There may be cheaper ways, but this was my first experience editing a video ever and they have quite a simple interface for it.
Total: $142 and around 14 days of working on it.
My experience with what each model does best:
- Gemini 3.1 pro was best at creating the 3d models in the game
- Composer 2 is fast and cheap, so food for quick iterations on small stuff and additions when you know what you want.
- GPT 5.5 did the heavy lifting in a lot of the more complex features, level editor, graphics, animations, etc.
- Opus 4.7 was my alternate choice when got frustrated with GPT 5.5, generally better at tasks that need a lot of research and digging into the code before building.
- Used Grok 4.20 for enemy AI logic, worked better than all other models.
