play-cljc VS euclidean

You could also compare it to the matrix functions in play-cljc (see also the API docs). It doesn't implement everything in your list though. I was originally using core.matrix but writing them from scratch made a big perf difference in my testing.

https://github.com/oakes/play-cljc i was wrong lol

https://github.com/oakes/play-cljc or https://github.com/oakes/play-clj - first is native or web and uses OpenGL, but is rather basic (but you'll have more control) - second wraps lwjgl, which in turn wraps OpenGL, but is a more mature framework giving you more support

I tried phaser recently. It is quite complete framework, so there is no need to reach for some specific purpose libraries. I went through https://phaser.io/tutorials/making-your-first-phaser-3-game but with shadow-cljs and it worked. The framework handles well low level stuff so the final source code is small. I have expanded the game from tutorial with sounds, custom graphics and it reached something like 150 lines of clojurescript code. However I wouldn't recommend it to someone who is just learning clojure. https://github.com/oakes/play-clj was really nice (and it was simple to build android app from it) but it's no longer maintained and I never used it's successor (https://github.com/oakes/play-cljc) which might be better option today.

https://github.com/weavejester/euclidean ... I don't think the goal was speed, there, but it's correct, simple, and I've used it to good effect.
