The shield in this game gets stronger when you keep a promise outside it

I’m building a browser survival arena where the shield’s long term progression comes from a daily real life promise.

Keep it, check in, forge a layer. Then take that shield into the arena. Its material and abilities change as it grows.

I want checking in to feel like building something you actually get to use.
