This is great, but as convenient as Obsidian Sync is, it'll never replace plain Git (for me) until it has unlimited version history:
> The retention period for your version history depends on your Obsidian Sync plan. On the Standard plan, notes are retained for 1 month, while on the Plus plan, they are kept for 12 months. After this period, older versions of your notes are deleted.
I have sync to support the amazing devs, and for convenience, and an automatic git-based backup that runs in the background. It's good to double dip sometimes
One thing Flash had that nothing else has really seemed to replicate as well since, is an environment that both coders and artists could use. I'd collaborate with an artist, they'd make their animations within an FLA, send it to me, and then I'd copy+paste into the project file, and it'd just work. I could even tweak their animations if need be to remove a frame here or there to tighten the animations and make it feel more fluid, etc.
That being said, I'm not sure I could go back to it now. I've been working with Love2D lately, and I prefer that (especially for the version control). FLA version control was always me going 'GameName-1.fla', 'GameName-2.fla', or when I got a little smarter 'GameName-Date.fla'. Eventually they let you split out the actionscript files into its own files, and that was better for version control, but you still had the binary mess of the FLA file.
But all these sprite-based game editors just can't handle the crazy intricate animations that vector-based Flash games could handle. Porting one of my old games (Clock Legends) that had hundreds of frames of hand drawn animation for a boss that filled the screen would be ridiculously huge nowadays, but the FLA for that was like 23MB, I believe (I'll need to hunt it down, I have it somewhere), and several MB of that were for the songs in the game.
Excited for this project though. It deserves to come back in some form.
