Cons
Con Documentation is lacking
Con No visual tools support
There's no level editor, asset viewer or any other visual tools in Loom SDK. Everything has to go through command line. I think it's fine if you really like typing.
Con Limited to interactive fiction
Twine is specialized to decision-based interactive fiction. Under the hood, a Twine game is just a flowchart for page transitions; the only way to add more complex behavior is to code it from scratch in JavaScript.
