The Thimbleweed Park interface-turned-free video game Delores: A Thimbleweed Park Mini-Adventure is now DRM-free on GOG, following its release on Epic and Steam last month.
Speaking of GOG, their summer sale (which ends June 15) is on, including a selection of Double Fine games and other adventure game stuff outside Mojo's sphere of influence, but which you should look into anyway. In my opinion, works like Primordia and Technobabylon stand comfortably shoulder-to-shoulder with the best LucasArts and its alumni ever swung-out.
