Feedbox

Feedbox is a 2D platform puzzle game inspired by the concept of a feedback loop. Players place blocks in a moving 2×2 grid that travels along a track. As the grid moves, the placed blocks leave behind a trail. That’s the feedback loop!

That trail doesn’t just sit there. Sometimes it turns into solid platforms; other times, a rotating trail opens up portals. To progress, players must carefully study how to place each block, solving the puzzle while trying to control the character and make it through the platforming challenges
