- picked a LÖVE tutorial ( http://osmstudios.com/tutorials/love2d-platformer-tutorial-part-1-the-basics ) based on a recommendation in the #TutorialJam Discord channel
- Downloaded and installed LÖVE
- Discovered what I probably should have known already: the LÖVE executable is the thing that *plays* the game, and the game itself is plaintext .lua files and assets and stuff in a folder
- Per advice on the wiki, set up Notepad++ with a keyboard shortcut to open the game in LÖVE directly from the editor window
- Started copy+pasting the tutorial code from the tutorial
- Reconsidered, started copy+pasting the comments only and retyping the code by hand to make the process more conscious and deliberate
- Made it through the black triangle moment (which, in this case, was a green rectangle) and onwards to installing the first library that this tutorial recommends.

Glancing ahead, I'm mostly done with Part 1 of this, and at that point I will have a minimal viable product. Part 2 is about reorganizing the code within that project to make more sense and be easier to expand on, which seems like what I want; Part 3 is about adding a bunch of assets, which I don't care about. So I'll probably aim to get parts 1 and 2 done next session and branch off in my own direction after that.

(...it's normal to immediately have an innumerable swarm of overambitious game ideas, right?)
