Very stylish and great evolution of mechanics! I thought the elevators transitioning between levels (and making me press start from within one) was such a nice touch. If i had one piece of feedback, it'd be that I wish some of the assets actually tiled their texture when scaling, like the ladder and chain - although it wouldn't be very realistic, it would better explain how you're able to climb them, and keep your pixel art scale consistent. Overall, nicely done!
