Tip: You can use Lunar Magic's Overworld Layer 3 Editing system to edit or create your own layer 3 images (castle bricks, fish, rocks) and apply unique effects per level via the Layer 3 Bypass in the main editor.
This is a fairly easy pit hack without a lot of originality. All of the rooms are quite short and contain mostly simple tricks, so it might be a good choice if you're new to pit hacks and looking for something easier to play. 3/5 from me.
I didn't find any breaks but I wouldn't be surprised if it was possible to reach the door in the upper left corner of the first level early and skip a portion of the hack, so I'd rather see it better blocked off or removed entirely. Apart from that, the very linear level design doesn't allow for breaks.
