I finally figured out how to set up a website on my own computer in my own house, something I'd been trying to do for a long time. So my game, Algebrain, is now available for you to try for free via that method at this URL, at least until I get a power outage:

https://algebrain.duckdns.org/

This is an improvement over the previous URL in that it's set up with SSL which means you can play with a game controller (e.g. an XBox controller or PS3/4/5 controller or whatever controller you may have for playing PC games), and also the multiplayer mode should work. Feedback would be appreciated both in terms of whether you have any problems accessing the website (e.g. warnings or errors) and also feedback on the game itself (i.e. is it fun, did you find any bugs, does it succeed as a proof of concept, etc). I'm definitely a noob at web admin so I probably screwed up something.

To see the controls for using a game controller, go here:

I also documentated the steps I had to go through to set up a website on my own computer in my own house:

It was frustrating how difficult it was compared to setting up a webpage through a service or through a server that you rent, which I've had little difficulty with in the past. To me that discrepancy is a gaping flaw in the structure of the internet. If we want a free, open, and democratic internet, then why should it be /easier/ to share my stuff from someone else's computer who I pay a fee to, rather than just sharing it from my own computer? The common advice I hear: "it's only $10/month" and "that's less than the cost of maintaining your own computer" is dogma as far as I'm concerned. The server I'm using is an old laptop with a broken screen which would otherwise be basically garbage, so my method is free and saves resources.
