Love the design and the split mechanic! It kept crashing for me too unfortunately. After maybe the 4th reload it seemed okay. I got stuck and couldn't figure out how to open the second door of the two next to each other. I feel like I walked around the whole of each open area but couldn't see anything to do. I'm sure I've just missed something though! Other thing is that it could be made clearer that a door is open - maybe by removing the bar that goes across it? Good work and hope you continue building it!
