Hi HN, I built a logic solver for the factory system in the game Arknights: Endfield. It handles circular dependencies (loops) and power grid calculation. Built with Astro and React. Feedback welcome!

I built Marvel Cosmic Lab to provide a high-quality, accessible platform for exploring deep space imagery and cosmic data. It’s designed for anyone curious about astronomy, from casual stargazers to space enthusiasts. I'd love to get the community's feedback on the UI and what features you'd like to see next (e.g., more real-time NASA data integration).

9types.org is a wonderful professional platform for the Enneagram. What unique advantages do you think the Enneagram test has over other psychological assessment tools in helping personal self-awareness and improving interpersonal relationships? Feel free to share your thoughts or questions.

I made a website that collects strategies, guides, and gameplay resources for the mobile game X-Clash. It includes hero information, puzzle solutions, combat tips, and other resources that players usually have to search across multiple platforms.

I’m sharing it here to get feedback on the site's structure, usability, content organization, and what additional tools or features might be helpful for players.

Any suggestions from the HN community are welcome.
