Phew, I just solved Harkonnen Force. That was really hard, but it made me feel smart after solving it 
I also beat Arty's levels which were both fun. I especially liked the Banjo-Kazooie themed one. I beat Wishing well, but my solution was very similar to Arty's latest back-route solution. Still a cool level. I really like the moss. Attached is the Harkonnen Force replay. I won't attach the rest of the replays because they're all very similar to ones already posted.

On Harkonnen Force, I manage to bypass completely the trap at the start.
