Farmhand and the case for open source games

Demo: https://jeremyckahn.github.io/farmhand/
Source code: https://github.com/jeremyckahn/farmhand

For as long as I can remember, I've always hide a hobby side project. For a long time I focused on open source animation tools, but more recently I've shifted my focus back to my true passion: Game development.

I've taken what I've learned as an open source web developer and applied it to an idea that I've been interested in for years.

A Reductive Approach to React Components

What follows is the result of Mad Science™ in React development, and is either a great idea or a terrible one. The jury is still out, and I will leave it up to the community to decide whether this is pragmatic or heresy.

I am a huge fan of React. I love the functional approach to app development and the parallels I see between the functional reactive programming model and game design. The established best practices largely make sense to me, particularly the parts about lifting state up to higher level-components. Anecdotally, I have found that lifting state all the way up to the highest level in a component hierarchy yields some really valuable benefits (which I have covered [elsewhere](https://gist.github.com/jeremyckahn/091aff8d1d62f661828c347750ae7644#2-all-
