Interesting take on the theme! I like the color coding for the switches and the SFX are all really polished! (also I only found out you can jump at the end of the game haha)
It's just a little annoying that switching is based on proximity and it's not always easy to swap with the target you intend to swap with (especially when the people move by themselves when not controlled). The 2.5D effect is nice but the foreground elements get in the way a bit of the puzzle elements.
Overall good job on getting out a prototype!
