It was fun to play and I got a perfect score after enough attempts, but there should really be a delay between the file getting to the destination and the next file spawning in, or a grace period where the file spawns in, doesn't move for half a second giving the player time to read the new saw layout, and then moves. Also, the ability to restart in the middle of the level would be nice since if I died once I was still forced to finish the level. Other than that though, you made a very well-polished 5-minute game.
