Interesting, but feels kinda slow and clunky. The jump is satisfying once you figure it out, But it feels like the map is a bit to cramped for it, as Lee is constantly bumping into things. She barely fits under some ledges. Further, once you figure out the jump, its the only way to get anywhere in any reasonable amount of time, so I would consider simply replacing the crouch-jump with a button.
Further Lee is nicely animated, nice work on that. The way that the robot can get their limbs/head stuck on ledges is fortunately infrequent enough to be funny and not annoying.
Finally, juggling all the key cards wasn't that fun, since Lee is so slow. Id recommend making it a collectable, or replacing them with switches to add some sort of door puzzle.
