These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Scrappy Mechanic / Some Dexterity Required: The controls, but this is mainly a problem for lefties. There's no option to change the settings, and it doesn't support the Circle Pad Pro, making the game even more difficult than it needs to be. The option to change the controls is added in the sequel, thankfully.
