## Prompt

```text
Let's develop a game.
The graphics can be either 2D or 3D; choose whichever makes the game systems and overall development easier to analyze and implement.
Personally, I’m imagining a 3D game with a side-scrolling action format.
I’d like to create a stylish atmosphere through the lighting and other elements, so I think 3D could enable more beautiful visuals—for example, streetlamps and lanterns.
The game I want to make is called CatWalk.
The name says it all.
A cat moves from side to side.
A catwalk stretches ahead, and the screen scrolls automatically. The player uses only simple controls, such as jumping, to clear obstacles and gaps while keeping pace with the scrolling speed. In a way, it might have a similar tension and system to Flappy Bird.
However, I want the graphics to feel mature, stylish, and atmospheric.
If possible, I’d love to show the cat moving, running, and jumping with graceful, fluid animation.
You can decide the stage’s setting, but starting with something straightforward, such as a nighttime street, would be fine.
I’d be very happy if a darker setting could make indirect lighting and similar effects look beautiful.
I understand that some things may be possible, impossible, or difficult.
Using my requests as a starting point, please develop something you think you can realistically make.
For now, make one stage playable through a single complete loop.
