Seems fun, may as well join in. I'm mostly focused on 2D singleplayer games, since that's what I personally enjoy. My projects are kind of a mix of Libre games and proprietary source-available games due to my line of work making it legally cumbersome to free everything I make, so I try to do it for just the larger / more obviously useful stuff.
I'm always open to re-licensing proprietary work by request though, in the event that someone is actually interested in re-using something.
Programming
Like @sndein, I also use LÖVE. I ran a comparison of various libre engines and frameworks a couple years back, (focused on development efficiency, comfort, and quality of documentation) LÖVE stole the show and I've been very happy with it since. The flexibility makes it ideal for iterating on s concept, which is a critical part of the development process.
For code editing, I use Neovim. It's also quite flexible, and generally gets out of my way which is what I want.
Currently, I host my code on Codeberg. I used to do so on Gitlab, so my projects are somewhat split between the two at the moment. I do have some concerns about Codeberg's long-term health though, so I also keep a comprehensive private archive elsewhere.
Art Production
I use a variety of tools, depending on the use-case. For higher-res work, I use Krita with a Huion Kamvas Pro 13. For pixel art, I use GrafX2 (with a mouse, for higher precision) and Deltapaint (an accessibility-focused art program for drawing by voice that I'm working on).
I'm not a purist when it comes to workflow though, my primary goal is to match a style and if it's more efficient to use a digital painting or 3D base for a piece of pixel art then I'll do just that.
Audio Production
Audio is probably my weakest point. I do most of my editing with Tenacity, and occasionally arrange more complex effects using LMMS. For music and musical sound effects / stings, these days I pay freelancers.
I use some CC stock assets from time to time, but I find that the process of finding good quality assets that meet my needs and are also stylistically consistent is a large timesink that consistently produces worse results than getting something made for the project.
Publishing
I have a website a decent hosting plan, so that site is the main place for downloading & playing my work today. Obviously I can't expect people to find--or trust--a random website on the internet though, so I also upload my games to Itch.io.
Other
In order to reduce the impact of my (current) disability, I use a variety of other tools including (but not limited to):
Dragonfly (with the Kaldi backend) - For voice control, particularly when writing large amounts of text, navigating my pc, or controlling Deltapaint.
Savant Elite2 foot pedal - This is mostly a navigational aid, allow me to easily pageup/pagedown.
...and AwesomeWM with a variety of adjustments to simplify the necessary inputs to do basic navigation and window management tasks.
