i can imagine how that would be bad if it were designed poorly then lol
It is designed poorly. You are often required to use special stickers in the field to solve "puzzles" and open paths but there's absolutely no hints of what you have to use.
For example, you have to freeze a lava path at a certain point in the game. It could be the Air Conditioner sticker, but it could just as well be the Shaved Ice sticker since they both freeze things. Oh and on that subject, there are stickers that are based on real-life objects called Thing Stickers. They're ridiculously overpowered and in the first half of the game they're pretty much the only way to win a boss battle.
For example, the world 3 boss spits poison at Mario at a certain point. Not only is there only one sticker that can counter this, the sponge sticker, but if you already used it up (because there's absolutely no way to know that you have to use this exact sticker at a certain point), it's back to Decalburg, the generic town which is also the only town in the game. And there you have to pay about 300 coins just to get that sticker back. Thank god that there's a world map because if there wasn't, I wouldn't even have bothered to finish the game. Why? Because the amount of times you have to return to Decalburg to do stuff is infinite.
The design choices in this game were so awful that it surprises me that there was absolutely no one that thought "hey wait, isn't this actually like really handicapped?"
