   I released an indie racing game (single dev)▲29

   It took me 20 months to develop it in my spare time. I used Unity game engine, I did not have any game dev experience before. It was more complex that I thought at the begining, I spent lots of time on promotion, marketing, founding company, learning about the legal aspects of different parts, for example music. Some parts were easier than I expected. Unity makes it very easy to build for all three operating systems (Win, MacOs, Linux), I am not sure why more game devs are not using this possibility. I also like working on Steam as distribution system. It is not exactly easy for a newcomer,…

   21st.dev▲1,211

   I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

   Unity like game editor running in pure WASM▲644

   In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

    Hi HN! I’ve been building a 2D game using a custom engine I wrote from scratch – no Unity, no frameworks. It’s fully self-funded and will be released commercially on Steam.
