Thanks for trying it. Yes this is very early - embarrassingly so!

Tech wise, this is using a stack I am experimenting with as my "go to" stack for simplicity.

Node.js/express

Postgres - using a free one on Vercel. No ORM just using 'pg' package. Migrations is a single .sql file I craft.

HTMX - where I have simple requirements for frontend interactions, that are server-bound.

Mithril - where I have more "react-like" requirements.

Digital Ocean App Platform $5/m.

Thanks necovek, I just spotted that myself! Probably best to remove that link as I don't have an about page yet. I have just pushed a commit to do that.

Thanks! The computer opponent still needs some work though, it is quite easy to beat (just leave the last 2 boxes of any "string" in the end game, and it will force it to open a new string for you).
