If possible, I'd suggest implementing a framerate limit for the demo. It was running at ~900fps on my PC, with CPU usage in the nineties! O.O I've now got it capped using the NVIDIA Control Panel (had to figure out how to enable the settings to allow this - was an interesting & educational journey xD). I liked what I'd played but was just too concerned about the CPU usage to relax with the demo......

I spent an hour with the demo, which was very interesting, and the hostess became a soul and could walk through the wall looking for new leads, great design. The puzzle elements are also great.I hope there is a contact number for me to join you,like email. The best....
