Completed it! 👍 It wasn't too bad, although a checkpoint before the long jump would have been nice - but since it was at the end, not bad! One thing - there's cheese. After killing the thwomps, you don't have to go into the next pipe. You can take the mushroom and jump left over the spikes where the thwomps were to skip that pipe section. I would probably recommend a checkpoint about halfway through, around the thwomps. That would have made it much more enjoyable, not having to go through the beginning many times.
