Hard mode was manageable for me. The jump to the long-jump powerup was probably the most difficult part, and I ended up piecing together that I could wall jump off the side for extra distance, use my umbrella when falling, put away umbrella to double jump, and use umbrella when falling, to successfully make the jump. May be unnecessary but it worked! Also, after struggling a lot at the end, I had to remind myself that you can hold jump to ascend airstreams faster with the umbrella. It was a good length, the layout was memorable, and there were a bunch of interesting platforming/puzzles I hadn't seen before. The secret areas were well hidden, and the bouncy one was awesome! The music fit a monochrome challenge tower perfectly. Liked the little story segments too. Good level
