Sounds like a useful resource. Be sure to post a link.
In a similar manner, I've been slowly maintaining a website showcasing open-source nim javascript games:
@hyl I'm happy to add any nim javascript game.
My searches on GitHub have not been very fruitful so far. Either games are not actually finished or they don't compile to Javascript. My incentive for making the site, in part, is to make it easier for future devs to find examples of nim js games.
The game you linked to is a great one! I'll place it up on the site this weekend.
In fact, I'll try to hunting for more on itch.io.
I looked through it again and you are right, there aren't very many. My apologies! Looking for "game" and limiting the language to nim gets about 134 hits ( https://github.com/search?l=Nim&q=game&type=Repositories), most of which are game engines or games not targeting js. I went through it and found dom's snake game which you already have ( https://github.com/dom96/snake ) and an incomplete one: https://github.com/bobgeis/nimSpaceRocks I did not go through all the engine repos to see if they had working js examples, but the ones I checked mostly did not have them. Itch.io or game jams may be better places to look, good luck!
I think I saw that there were a lot of game engines, saw that some had examples and that some offered js targets, and after spot checking a couple (including nico) assumed that there were more js games than there really were. It could be that people who want to make games in the browser tend to use javascript or some other language and not nim. That said, someone could probably use karax to whip up a 2048 or one of these https://www.chiark.greenend.org.uk/~sgtatham/puzzles/
Thanks for the suggestions!
Both the new game (smalltrek) and the "Add Game" form are up on the nimgame.online website.
