Do people traditionally code sign their entries to avoid the ominous warnings about unsigned code? If so how do others sign their code?
Actually Godot (the engine I prefer for game dev) use a very very python like scripting language.
Maybe in a future game you could try it. It has one of the easiest web export that I have seen.
In fact I use the web export in jams during development so other not technical members of the team (artists, sound designers) can easily see their art/audio in game.
Installing a game through the itch.io app means signing isn't necessary. (Wish I could find a better link than that.) But of course that depends on the player having already installed the app before installing your game, so, yeah, target a web version if you can.
