Show HN: Vein, a minimalist open-source resource management game

Recently I've been working on Vein, a small open-source resource management game built with Godot.

I've always loved resource management board games, and I wanted to see how minimal I could make one. The core idea is simple: keep the heart beating by supplying it with the resources it demands. I tried to strip the mechanics down as much as possible while still leaving room for interesting decisions, and I added a short tutorial to help players get started.

The problem is that I still don't feel like I've found the right gameplay loop. It works, but it isn't yet the game I imagined. I'd really appreciate any feedback—whether it's about the mechanics, pacing, tutorial, UI, or anything else that stands out. I'm especially interested in ideas for making the core loop deeper without making the game more complicated.

Most of the development was done with Claude Sonnet as a coding partner, while I focused on the design, gameplay, and iteration. The game engine is Godot.
