The core puzzle idea was decent. It took a while to figure things out. The biggest issue is that you have buttons with arrows on them next to the buttons to start and restart. I kept clicking on them and the other buttons trying to get something to happen. Eventually I thought to use the keyboard and that worked. If the buttons are not meant to move the character, then they should be changed to not be clickable buttons. It is good to tell/show people the controls, but as buttons they looked like the controls themselves, and not instructions. I played a few times and managed to get several people out. Things flashed fairly fast, and I wasn't following everything, but got the general idea of what was happening.
