Show HN: Shoot-em-up Deck Building game
Hey, I've shared this game while it was still a work in progress in one of the Tell HN threads. I was pleasantly surprised that a lot of people tried it, and I got some positive feedback and constructive criticism.
Anyway, I found a gamedev library I really like - Kaplay [1]. What I like about it is that easy things are easy. Meaning I could have fun building the game without learning (or fighting) a new tool. I always wanted to make games, but this is the first one I actually did.
And I have to tell you - game development sparks joy! It combines so many things (game design, programming, art, sounds, UI...), and it is incredibly fun.
The game is a combination of action and turn-based gameplay. Probably a too ambitious goal, but I think I managed to make a fun little game. If you are not sure what I'm talking about, try playing the tutorial, it should help. There is also a global leaderboard, which is dominated by my friend, and I would appreciate if someone can dethrone him :)
It is completely free. I'm thinking of open sourcing it, but the code isn't up to my regular standards, as I was learning on the go. Also, I was more excited about adding stuff than going back and refactoring. So I'm still deciding on that one.
Before you ask, no, I haven't vibe-coded it. For me personally, that would mean delegating the fun stuff to something else. I’ve been working on it for about a month, in the evenings after my kid is asleep.
All feedback is appreciated!

P.S. I also plan a blog post or two about it. I already started an interactive demo on how missiles are coded.

Show HN: Roma Data Pipeline – Open-Source Ancient Rome Data
I created a data pipeline that aggregates data from
Pleiades Stanfords ORBIS Harvards DARMC AWMC ToposText WikiData
and then normalizes it all into a single schema and builds a SQLite database.
I did this in support of a free app I developed that gives a Google/Apple maps like experience for ancient Rome.
I had a difficult time finding good, joined data sources and created my own. I thought I might opensource it with the hope that 1) Others may find some value in this (especially academics) 2) Others can contribute and grow the breadth and depth of the data
Open to all feedback or thoughts and also any points to relevant datasets or similar projects that might exist

Show HN: Ledger – A private workspace for Engineering Managers
Hi HN
I’m an Engineering Manager, and over the years I struggled with one recurring problem: important management signals (1:1 notes, concerns, feedback, missed check-ins, context, achievements) were always scattered across tools or stuck in my head.
Ledger is a tool I started building to solve that for myself: • One private space for EMs (not HR, not employees) • Capture 1:1 notes, concerns, and follow-ups • Simple tracking of people journey, not tickets • Optional AI summaries to support reviews and coaching (very conservative by design)
The goal isn’t to replace judgment or conversations, but just to reduce memory bias and make better decisions with less mental load.
It’s early, opinionated, and shaped by real EM work rather than frameworks. I’d love feedback, especially from people managing engineers or managers of managers.

Happy to answer questions or discuss what shouldn’t exist in tools like this.

Show HN: Simboba – Evals in under 5 mins
Hi HN,
I built Simboba because we needed something for our own product, and I wanted to explore how dev tools change with AI coding assistants.
The hardest part of evals is creating good annotated test cases. So I focused on getting users there with the power of AI coding assistants.
How it works:
- AI drafts datasets from your codebase - Web UI to review and refine cases - Everything tracked in git - Multi-turn conversation support - LLM-as-judge + deterministic checks (e.g. was tool xyz called) - Evals run as simple Python scripts
The AI coding assistant angle: I wanted users running customised evals in 5 minutes, not just a generic example. Started with a CLI command that generates a prompt for Claude Code / Cursor. That felt like too much friction. Then tried a separate markdown file with instructions, but AI tools didn't find this easily.
What worked: clear instructions in the README plus structured schemas (Pydantic). The AI reads the README, understands your codebase, the structure required for the package and drafts a real dataset for your product. Then writes the eval script.
I'd love to know what you think, and happy to answer questions!
