If your friend group or family happens to include multiple Playdate owners, there’s now a cute way to chat amongst yourselves right within the device. Jon Simantov, the developer who gave us Cranky Cove, has released an app called helloyellow where you can send voice messages, create group chats and share achievements with anyone you’ve added as a friend. It’s available to download from itch.io for free, with some limitations, or $5 to get the full version. Now, excuse me while I lament being the only person in my circle with a passion for weird little gadgets.
