Thanks for playing and providing feedback! There was tutorial text in the first room but it disappeared in the build version. For the lever rooms, the idea was that you were supposed to adjust the contrast and brightness settings on the monitor and an up or down arrow would appear on the colored panel above letting you know what direction to push the lever in. However, I can see how this would not be clear at all without the text. Thanks for letting me know about the respawning bug, I'll have to look into that!
