Jonathan Blow, lead designer on The Witness, revealed a small glimpse of one of his upcoming games during a presentation at Reboot Develop.
"This is a work-in-progress," Blow explained. "These are not final visuals, but it's a nice little grid-based game. I've got a guy who can run around and push blocks and stuff."
The demo — meant to show off the engine Blow has been building for the past year — showed off a single level from the unannounced project, which Blow described as "not remotely final."
