The figurines are an important point. DON'T COLLECT THEM. The Minish Cap is at the top of every list of Worst Zelda Quests due to the random nature of collecting, the high number, the high rupee cost, the extreme length, and the puny reward. Yes, it beats out the Korok poo on every list, it is a nightmare.
Also, depending on what console you're using to play it, there are several quality of life improvements you could make. For instance, if you have the physical cartridge, the original Game Boy Advance is more comfortable to play than the SP (with adequate light or ips screen replacement) if you have the cart, you probably have money to burn so the you could throw it in a game boy player and use Swiss to tweak the play to your liking. Swiss would also be useful for the game boy interface which will allow you to cut down on the horrible input lag provided you run the game on a CRT. The setup gets a bit more expensive if you're looking for comfort considering you should never use a GBP with the Game Cube controller as the D-pad sucks. You'd need to grab a hori pad or solder a SNES controller to the Game Cube controller innards. I believe Minish Cap also has stereo to which the GBP will give you full access.
If you're using an e̶m̶- sorry, a COMPUTER, you'll have access to a part of the same things, but there's still a matter of getting a decent gamepad hooked up to it that is compatible with your computer software. You're likely playing on a switch and if so, you want to plan handheld mode since that's as close as you'll get to authentic. But if you're really die, hard committed and money is no object, they're really truly is only one way to play The Minish Cap correctly. Game Boy Micro.
