Interesting conceit! I didn't mind the idea of having to read ahead. I'm not quite sure it strictly adheres to the jam theme--I didn't personally get the complete sense I was joining the rooms together as an intentional choice on my part. But the presentation was quite good!
A few things I'll note:
1) The shortcut provided in the zip file doesn't work, since it is looking for the pathway on the original C:\ Drive it was made on. Launching the game application from the Bin folder does work, however.
2) The first plasma puzzle has some kinks to iron out in it. Having a clearer understanding of when the block would take a plasma ball left, downward, or right, would be useful. I wasn't clear whether or not it going downward as intentional or not even after it passed through the block as well.
3) Every time I went into the room after the first plasma puzzle, the screen would remain black and I would fall straight down. I don't know whether that was intended or not either!
