A cool idea! I could see this being interesting to add more levels to. One idea/strategy for the player could be following the ‘enemies’ around, like a guide that you can’t touch - that might setup some nice risk/reward if the goal was getting to the end fast-enough. I could also see you explore some subtle clues/hints when there are nearby objects from the ‘other’ vision.
I’m not sure if there was supposed to audio (b/c there was a credit)? Maybe it was just my machine/browser not handling it? (firefox on linux)
