I hope more people play this. The puzzle design is really quite good with a nice mixture of thinking and skilful execution. I'm not sure I did the finally level correctly as I set up what I thought was the solution but found out I couldn't jump off the box in the spikes. Nevertheless, I did solve it in the end. The mechanics space of the switches combined with the ability to jump on ghosts really opens the levels to a lot of ideas when trying to solve.
Nice entry, I had good fun completing this one.
