Kenney 1-Bit Pack “includes over 1,000 different tiles, characters, objects and items. It’s perfect for roguelike and RPG in any setting (fantasy, feudal Japan, modern, sci-fi etc.) and even comes with tiles for UI, platformers and puzzle games. Perfect for prototyping! Also includes a monochrome (black and white) version, plus versions with a transparent background.”
I wonder whether it would be easy to write a Gridmapper like editor that would quickly allow us to create maps using the keyboard. And town and dungeon and all sorts of map generators using that.
And Text Mapper itself is an example of an application that has been made a gazillion times more joyful to use once I got the Gnomeyland icons by Gregory MacKenzie added.
