I don't browse tumblr so I only have peoples twitter handles to share. Here is mine @tentril and hopefully I will be posting more about gamedev stuff in the future. Here are cooler people to follow.
@DreamsBell - Making Jack the Reaper, a Kirby inspired platformer where you play as a cute grim reaper.
@rabbit_nabokov - Making the Momodora series of games. I guess you'd call them Metroidvania?
@SinksAdventure - Made Crowtel, a cute platformer about a crow running a hotel!
@fancydrak - Has a goofy pet sim and a few other small projects, but mainly is working on Item Haver
