The first version of SRB2 that I had played was version Final Demo 1.09.4 that I found on an old Flash games website from my childhood that's now gone. I don't remember if it was the latest version at that time or if version 2.0 was already available on the official website, but I do remember that I used to check the official website a lot. I remember forgetting about the game for a few years during the 2.0 period because of no new updates and getting completely surprised when I discovered that 2.0.7 was out, and thinking that SRB2 was discontinued when the website shut down during the SOPA strike. Often when I randomly think about SRB2 music tracks I find that it's from the 2.1 soundtrack; perhaps it has stuck with me after so many years playing the game. But the 2.2 soundtrack is excellent and 100% better than the 2.1 soundtrack. Actually, version 2.2 is such an upgrade from 2.1, the dedication of the developers and attention to details really show. Version 2.1 felt like a nice free fan game, but version 2.2 feels like a polished indie game, from the menus to the level design and music and basically everything (except the ancient netcode).
