In this post I will go through every single line of my 1 kilobyte piano and explain how some of the trickier parts work. The whole thing is open source on GitHub and has a some improvements since my JS1024 submission. So please continue reading and let’s make sweet music together!
Here’s 1Keys running live in a CodePen for you to mess around with. It can be played with either the mouse or keyboard.
Months ago, when I heard that the legendary JS1k game jam would not be continuing, I talked it over with some other devs and decided to help fill the void we would host a 2k game jam on itch called 2kPlus Jam. The primary goal of this comp was to create a game that fits entirely in a 2 kilobyte zip file. That is incredibly small, for point of reference a 3.5 floppy disk could hold over 700 of these games.
The theme for the game jam was “Shift” which I incorporated by shifting the hue for the world’s color when the player crosses a checkpoint. I imagined that crossing a checkpoint was fictionally like shifting or jumping into a new dimension with a different hue, which is how I came up with the name “Hue Jumper”.
For 2kPlus jam I made a 3D racing game that fits in 2 kilobyte zip! It includes physics, controls, rendering engine, and procedural level generator. The code is extremely dense and clean as I went through many iterations to fit everything. I also spent an immense amount of time polishing the look and feel. You can play the game in browser, or view the code on GitHub. I am working on a post that will go into some technical detail about how my game works. Also, check the other submissions to 2kPlus jam, there are some mind blowing entries!
Time REWINDS you die… but your PREVIOUS LIVES remain.
I used the theme by having ghosts of your previous lives return to help you after each death. There is also a juggling mechanic like the Twin Bee / Stinger series of games where you can juggle an egg for massive bonus points. The level is procedurally generated every time you start a new game and gets progressively more difficult over time.
The game can be played with keyboard, mouse, or gamepad in several different configurations. There are 2 ways to shoot, hold fire for fully auto, or wait to charge up a powerful blast.
