It unsettled me a lot about just how much work was put into making the JavaScript version of this work instead of a purely Python version, due to how OpenCV works. I wonder how universal the laggy OpenCV thing is, because my friend faced it too when working on an OpenCV application. Is it so unavoidable that the only option is to not use Python? I really hope that there is another way of going about this.
Anyways, I am very glad that you put in all that effort to make the JavaScript version work well. Working under limitations is sometimes cool. I remember having to figure out how PyTorch evaluated neural networks, and having to convert the PyTorch neural network into Java code that could evaluate the model without any external libraries (it was very inefficient) for a Java code competition. Although there may have been a better way, what I did was good enough.
A few weeks ago, I tried to compile Clang to WebAssembly, but got several different errors, and tried fixing a lot of them, but some of them seemed kind of impossible to fix, so I thought I would try again at a later date. However it seems I will not need to try again. I feel angry that someone made a convenient solution before I did, but also happy, because this probably implies that they made a consistent process to compile Clang for WASM.
I looked up what "the sentinel" was, and it turns out it was a game in 1986, that works on the BBC Micro and Commodore 64, and has 3D graphics! I didnt even know it was possible to do that on average computers in 1986!
The online SAT was much easier than the written version, because (1) You don't have to read big essays anymore in the reading part, and (2) both math sections have the Desmos graphing calculator, with absolutely no features taken out. Desmos is far more convenient to use than a TI-84 for many things, so it made all the problems, especially the hard ones, much easier.
Also, in my opinion, their Bluebook testing software is actually pretty good, especially compared to other digital testing software I had to use over the years, like ClearSight.
I am so impressed that you were able to figure so many things out in the puzzle! I feel like I would never be able to do that, but I feel like all that is needed is a lot of patience, a lot of time, and a lot of deep thought.
