Does it ever feel like you need superpowers, money, or an audience to be a hero? Not so in Intercom, by J. J. Morgan. You can be a real hero by simply pressing space to beep.
You find Patrick, a laboratory assistant, stuck blinded in his lab. Using the beeps of your intercom, you invent a beep-based language to help Patrick sense and escape the traps of the lab. With a few short levels of adventure, and coming up with new beep sequences, you'll be able to get him to safety.
This game came in 2nd place in the GMTK Jam 2019, with the theme "only one," which is masterfully applied by only having one way for you to interact with Patrick. (A more-polished variant of this game would be perfect for a particular playful handheld I'm excited for.) It's short and sweet; you'll be through it in 5 minutes.
