First draft of the derplore main timeline is done! I actually have other plans for the derplore headcanon now though, so don't fret if something you wanted to know about isn't mentioned when the main timeline releases.
There's a fun little platformer roguelike called Rogue Glitch that released 3 days ago. It's free on steam and it's super fun. It doesn't play like a "free to play" game at all, the only thing you can buy is online multiplayer.
