   Tiny Moon – Swift library to calculate the moon phase▲106

   Tiny Moon is a tiny Swift library to calculate the moon phase for any given date, works super fast, and works completely offline. All of this started when I realized that we only have 12, sometimes 13, full moon's in a year. That doesn’t seem like that many. I set out to build a MacOS app to remind me when a full moon occurs, so that I could take a moment and step outside to appreciate it. The MacOS app I ended up creating can be found at https://apps.apple.com/us/app/tiny-moon/id6502374344 along with the source code [0], all powered by the Tiny Moon library. I…

    Mini Metroidvania in 13KB of JavaScript▲238

    As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://github.com/arikwex/infernal-sigil NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller (https://github.com/lifthrasiir/roadroller) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural…
