Ask HN: What Are You Working On? (Nov 2025)

I've been working on two game development projects for the past couple of years.

One project is for building rhythm games in multiple game engines and multiple platforms. Currently, it works in Unity, Unreal, Godot, SDL (or any C++ game engine), and MonoGame (or any C# game engine), and runs on Windows, macOS, and Linux. I'm working on adding Love2d (or any Lua game engine) and Bevy (or any Rust game engine). I have a few local prototypes of it working in Unity and Godot, but nothing public yet. Still trying to figure out what kind of game I want to make with it.

The other is a general purpose game engine in C++ with SDL. It's far enough along that I'm building games in it, but it's more of an exploration into how games are made than a replacement for Unity or Godot. I suppose it could be eventually, but I'm trying to be realistic with what it can do. One thing I'm pretty happy with regarding this engine is that one of the demo repos will automatically build to WebGL and publish to itch.io when changes are pushed.

I'm working on https://teeming.ai, trying to solve the information asymmetry problem in the job market.

The project has been a huge learning curve for me - I started out as a skeptic of how generative AI could solve real problems (rather than just create noise) but now think that, like the internet, it can create a new kind of abundance that will be harnessable in all sorts of interesting ways.

I’m building Streamlit for Java. https://javelit.io https://github.com/javelit/javelit

I maintain a dev log: https://world.hey.com/cdecatheu/javelit-diary-00-building-a-...

And here’s an article about the project by a Google Cloud devrel :)

I created this recently but have let it fallow in the last month. Planning to update it over the next few days / weeks. There are a crazy number of directions I could take it.

Would be great to collaborate with others on it. In particular I want to explore building the "alpha arena for AI house price prediction"

I'm adding a Shortcuts‑like UI with Hyperscript syntax for defining logic to the app builder I'm building.
