It did take me several tries to do this puzzle.
I used the mouse completely, timing is also necessary.
If you position the arrowhead at the correct place and at the correct time; then click on the place you want it to go - you don't need to move it manually.
I cannot find my saves for the prison chapter as well as 3 more chapters. Weird.
If you want a saved game, let's wait for someone else that has a complete set.
I found the complete set. <whew>
The saved game is sent.
