Hide and Seek

This is my first attempt at making a hide and seek map. I didn't really know which direction to go in, so I added a little bit of everything. There are static, button/switch, sensor, and hammer accessed spots. Basically, anything I came up with, I built into this challenge. Hiders activate the green switch (marked 'H') when ready. To begin the countdown, the seeker enters the confinement cell (marked 'S') and presses the button. The hiders will then be released, and the seeker locked away for 2 minutes. The challenge timer starts when the seeker is released. (Yes, this means nothing can be destroyed during the hiding phase.) (And yes, there are hiding spots only accessible by destroying stuff.) After 5 minutes, an observer bot will appear in the centre of the map. At this time, 4 master switches will also become accessible. These switches are hidden across the map, varying in difficulty to locate. Once all 4 switches are activated, the screen in the laboratory will show the sequence code to finish the challenge. Memorise this code and enter it into the terminal at the police station to complete the challenge! That, or find one of two hidden, instant-win buttons. I'm still inexperienced, and this challenge is a mess, so things do break sometimes. I've tried to make it as reliable as possible, but it's still far from perfect. If you do notice any issues, then... cool, I guess, welcome to the club.
