Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Looking for small finished games developed in Haskell
My ludum-dare 34 entry does have scrolling, and some images which are only visible in some screens but not others. I didn't do any effort to load and unload them as required though, I just keep everything loaded at all times. One potential difficulty is that this game uses Haste to compile Haskell to JavaScript, soI don't know if your framework supports that.

Haskell to JS
There are quite a few approaches. Personally, I have only tried Haste, once, but I do recommend it, as it was quite easy to get started (I hear that compiling ghcjs can be pretty difficult by comparison) and it was also very easy to interact with existing JS libraries.

Options for a frontend of demo for a toy app
ghcjs is the way to go for you, and soon it might be asterius. i do not know how hard it is to set ghcjs up without a framework. but frameworks like obelisk (based on reflex-dom), shpadoinkle, and miso automate that for. i personally like obelisk for its functional reactive programming but it can get awkward and get in your way. so if gui programming is just a means to the end of this one small application and you are not really interested in it nor functional reactive programming, shpadoinkle or miso might suit you better. miso implements the elm architecture (also "TEA", "functional model view controller") and shpadoinkle implements something directly equivalent to the elm architecture. but shpadoinkle achieves more composable widgets by minimalizing the elm architecture. so i recommend shpadoinkle for its better concept although miso is more mature.

hint: Runtime Haskell interpreter
Also, hint uses unsafeCoerce, and thus implicitly relies on an assumption about how values are represented at runtime. Namely, if a program P is interpreting an expression E of type A, hint assumes that the value of type A produced by the ghc interpreter has the same representation as the values of type A which are manipulated by program P. This is not guaranteed to be the case, since P has been compiled by the compiler portion of ghc while E has been evaluated by the interpreter portion of ghc. This means the ghc devs had to carefully craft their compiler and interpreters to match. When targetting the browser, a Haskell-to-js or Haskell-to-wasm compiler such as Asterius modifies ghc's code-generator so it produces js or wasm code. You would thus also need to tweak the interpreter so that it produces js or wasm values which match what the modified code-generator outputs. Or you could restrict yourself to the hint's less expressive eval :: String -> String API.

M1Pro Woes
We found a post where someone had a similar issue (here), but the fix in that issue doesn't help: using `ar` from `binutils` causes link errors like this instead:

Pandoc in the browser w/ lua (possible contract gig?)
https://github.com/tweag/asterius/issues/851 (asterius has a demo, but no source, and I -assume no lua filter support)

Is GHCJS stuck on GHC 8.6.5?
Another option is Asterius. I'm not familiar with the current state, and it's not had active development for about 3 months now, either, so it may be in the same boat? But I think the big disadvantage of Asterius is that there's just a lot less usage, and therefore a lot less testing with the whole Haskell ecosystem, versus GHCJS which has been a fixture for a while and where loads of people have thought about compatibility for years.

WebAssembly Studio
I've played around with Haskell via the Asteruis project : https://github.com/tweag/asterius
Also emscripten of course, for C/C++.
What are some alternatives?
proposals - Tracking WebAssembly proposals
ajhc - A fork of jhc. And also a Haskell compiler.
pcf - A small compiler for PCF
hyper-haskell-server - The strongly hyped Haskell interpreter.
sjsp
dhall - Maintainable configuration files
haste-compiler - A GHC-based Haskell to JavaScript compiler
perspective - A data visualization and analytics component, especially well-suited for large and/or streaming datasets.
accelerate - Embedded language for high-performance array computations
egison-tutorial - The Egison tutorial
annah - Distributed programming language that desugars to Morte
