i'm confused as to why you didn't credit 'the last door' as one of if not your primary inspiration(s)
one thing they did that i wish you'd done was make it so when you've already traversed a connection, on subsequent traversals, double-clicking the hook would instantly transport rather than forcing you wait for the very slow walk.
the travel mechanic wouldn't be enough for me to give this less than a four. but you not mentioning your inspiration and giving credit where credit is due definitely is.
also, i kind of predict you will deny the influence of that game. i'm looking forward to that response.
