JS13kGames: a game jam under 13kB
https://straker.github.io/kontra/ Kontra is a lightweight JavaScript gaming micro-library specially optimized to be used for the js13kGame competition. Kontra aims to implement basic game components like asset loading, user inputs, loading loops, and sprites. This allows developers to spend less time worrying about smaller components and only focus on their personal game designs.

Cat Goric: Escape from the Warp Chamber - Post-Mortem
I was still in doubt about using Kontra or Replay as the game engine. Still, in the end, I decided to use Kontra for having more built-in features I needed, and also because I had used it in a previous js13k game.

Build a tiny game for JS13K with Kontra.js
If you've never done anything like this, or even coded much JavaScript before, it can be a little intimidating. Here's a quick little tutorial how to build this suh-weeet game using Kontra.js (a tiny game library made just for JS13) plus a few lines of code:

Cat Goric: Escape from the Warp Chamber - Post-Mortem
On the other hand, for the background, I spent a whole week in research. It all started after xem released a tool called midi2array. It led me to rethink something I wanted since I first participated in js13k: using WolframTones to generate music for the game. Wolfram can export in MIDI format, so I needed some tiny lib to play this .mid file. In the end, I didn't use xem's tool, but instead, the tool he used to extract notes from MIDI: Jasmid. So after generating a lot of songs, Wolfram finally output a melody that, when played in Jasmid's piano synthesizer, matched the game pace! One of the best moments of this jam!
