Extended is everything what Basic offers + cheats and experimental (usually bugged) features. Public & itch.io versions are considered "stable", while on Patreon you get access to the newest beta releases. So Patreon is currently on v32a and soon I'm releasing v32b, while itch.io is currently stuck on v31d and will be updated to v32b once I release v33 on Patreon (in December).
