You are supposed to realize that you can grab things, including the picture of behind (the rule that prohibits the movement), and then be able to start moving around
OHHHHH wow that's actually really cool!! That's 100% on me, I am not running on a lot of sleep, so I must have missed clicking 'e' on the picture behind me, and instead elected to just hurl the coffee cup at things. I played it again and it's a really innovative mechanic, great work and apologies!
