I edited it a bit to be more vague and removed mention of items not mentioned in the article. the rest isnt really a spoiler and only describes how I dont think the upgraded bubble mentioned in the article is even needed for any of the bubble jumps, though it would be harder. The room descriptions will be fully meaningless to anyone who hasnt spent hours scrutinizing every pixel, and 3 dog is literally just identifying a room with 3 dogs in it that are immediately visible on the room load. the game is a 2d platform/metroidvania with no written or spoken story.
