THEME: Start with nothing


  • there's a character with a preset script of directions he will take. We get those as an overlay
  • our job is to make the hero reach somewhere in the initially empty map by adding tiles

social twist:

  • if each set of movements is driven by a seed of a random number generator, we can map different solutions of the same movements to different ending maps.

jsonlish stringify

jsonlines and similar formats where each payload is stored as unindented JSON chunks divided by newlines are great for complex systems.

My application is more to aid in exploring large JSON files and copying/pasting, chunks in the editor, therefore made this small JSON stringifier that breaks the 1st level of arrays and objects with newlines,while returning valid JSON.

The placement of commas is intentional. This way one can find the item, right, shift+end, copy.

You can’t perform that action at this time.
