While I posted a solution that would do this, I'd call this premature optimization. The only time I'd even consider doing this is in a hot path. Here's a good reason to focus on branchless programming: https://github.com/neuecc/Utf8Json.

If my game state was smaller I would go for https://github.com/neuecc/Utf8Json and serde_json combination. Would save me some time with rmp_serde customization.

Looking for suggestions on storing the level/brick data in an Arkanoid/Brickz type of game.

I think JSON is used reasonably often under the hood for various things in Unity, I certainly use it in all my games. The builtin JSONUtility can do the job, but there are some edge cases (serializing lists without a base class, for example) where it falls over. LitJSON is a simple but comprehensive option if you need more power.
