I built a mobile-first card game design tool. Curious how you all approach core loops and playtest iteration?

I've been a digital designer for years and have circled the same idea for a long time. Most card tools (Dextrous, NanDeck) are great at making cards look polished, but they put layout first. I wanted something that keeps game design front and center, so you can get from idea to the playtest table fast.

So I built one. It's a very early beta with a lot more planned, and I'm sharing it here mostly to find out whether this direction resonates or not.

A few things I'd love this community's take on:

- Does it make sense to you to put the core loop front and center like this?

- What would you expect from a tool like this?

- How do you currently approach core loops, design, and playtest iteration?

If you want to look, it's here: https://play.eerieisland.com/. It's a closed beta, so comment or DM me and I'll get you an invite. Totally fine if it's not your thing, I'm really just after honest thoughts.
