dirt graphic is ugly too, I'm afraid
yeah i know, i'm trying to improve them at the moment
those boxes are bland too
they're called reaction blocks and they do something when you stand on switches or cuts wires/ropes connected to it.
in this case it would make the first four blocks go down so the player can pass and make the block on the right go up so it'd be an elevator. the switch on the high platform does the same thing.
