Love the concept - "every piece you fit, two more appear" is such a clean, literal take on chain reaction, and it naturally ramps up difficulty exactly as the jam description promises. I did have real trouble with the drag interaction; slow drags seemed to pan the camera instead of grabbing a piece, and only a quick decisive drag actually picked one up. Once I got the gesture right the pieces snapped together nicely! Worth polishing the pickup feel so more players get to see the escalation.
