Chronis

Someone is in the middle of a block dropping puzzle game, but they're about to lose. It is inevitable. Wait, what is that? A time rift?! Maybe you could use that to prolong their game... Click to create a time rift, drag away from the center to rewind time. Release to confirm. You can get fine-grained control of the rewind point by dragging perpendicularly away from the main axis (for example, click and drag horizontally to get near the target you want, then drag up/down to fine-tune the selection).
