Requires mouse & keyboard

This started off as: "I wonder if I can get the ZX Spectrum font into pico-8?"
I then realised that 16 chars per line isn't particularly practical, and wrote a font editor.

Features:

edit, save, export fonts for use in pico-8
change width & height of font characters
adjust width per character
cut, copy, paste, undo, nudge
8 internal save slots
exports a .txt file to desktop that will run in pico-8 to use the font in other projects
uses ZX Spectrum font as initial template

Limitations:

save/export won't work in browser
only edits the main 96 characters (i.e. Spectrum font)
no undo on the file screen!
fonts are saved internally to cart rom on exiting the file screen, cart must be saved to keep changes.
can't load external fonts
exported code is verbose, but I wanted to keep things readable.

Another Space Invaders clone! I just fancied having a go at writing one, and then the particles and themes happened.

Bonus points if you get all the references...

CTRL+1 - move current line up
CTRL+2 - move current line down

Discovered by accident this morning. I've done a quick search, but can't find it mentioned anywhere.

Voronoi shader thing

Left/Right: change shader
Up/Down: change number of nodes
z: shuffle nodes

A cart for messing around with raster patterns. I love drawing shapes without actually drawing shapes, if you see what I mean.
The "shaders" are just simple formulas to select the pixel colour based on distance to the nearest two nodes.
Interlaced scan speed adapts when the number of nodes changes.

2022-03-09 - slight speed improvements, tweaked the adaptive bit.

First uploaded cart... only took me two years to get around to it.

This started out as a single chain. I read something on here (sorry, can't remember who by!) about cloth simulation and pulling both ends, and this is what I came up with. Not really cloth simulation, but I am still amazed that simple rules can create something so fluid-looking. The "wiggle" was mainly added to stop new links getting stuck, but it makes the whole thing look as though it is underwater.

I'm not planning a jellyfish-based game. Yet.
