There is a way to cheat with the Amiibos. The Samus gives you a permanent +100 energy and the Emmi +10 missiles then you can change your clock in the Switch settings (you can only scan the Amiibo once every 24 hours) and Amiibo will heal you/replenish your missiles. It works during boss fights too. Pause your game, change the clock, scan Amiibo. Repeat.It's a great game, but I do believe it will turn a lot of casuals away. The boss fights were much harder than all the previous metroids. The only plus side for casual gamers is that you continue right next to the boss fight after you die.
If you don't have the Amiibo, look for ways online to create your own NFC tag.
