Thanks a lot for the feedback! :)
I think people underestimate HTML, not because it is powerful itself, but at the end of the day it is just a container. You can write very performant code using javascript rendered in canvas 2D.
https://codepen.io/soulwire/pen/DdGRYG This is a very old example of a very performant sim, you might like, written in it. Short, clean, understandable code can produce really fluid results. I hope that people can also look at it and realize it really isn't that daunting as it originally looks, particularly if you really like coding :) .
Sorry for the long reply 🦆 Just want to make sure that people aren't scared of the tools that exist, and sometimes a massive game engine that can create incredible things, is not needed, and a smaller scope and breadth of tools actually is a benefit. Fewer buttons, fewer abstractions, more control!
Hope that helps, best of luck in the jam!
