I'm at the second major boss and my impressions so far are not particular positive because of the games terrible control layout. All I have is joycons since I don't really play switch games much, but this game was not made for them. For example if you want to shoot a bunch of missiles at a boss you gotta hold L1 to aim, R1 to enable missiles (which is not a toggle), and then mash the one face button. There's no loose lock-on or anything either while aiming. It ends up really hurting my hands. I could consider getting another controller but that's money and what they should have done is just let me configure my own controls. There's not even any sort of options related to that.
So I quoted you above saying it feels pretty good on a Switch Pro controller. I completely forgot about a feature that the Switch has that is for some reason totally hidden. From the Switch's home menu, you can go to System Settings - Controllers and Sensors - Change Button Mapping and set up a handful of different profiles. This unfortunately doesn't change the in-game prompts and such so you have to remember that you changed Y to ZR or something crazy like that, but you can change up buttons.
It's probably too late for this game but may come in handy in the future.
I'm aware of this and it's still BS. Not really an acceptable solution to be frank as it changes it across all games, and wouldn't fix/address the issues I had with the game. The controls do start to feel better once you get the Storm missiles since precision aiming isn't as important than. But the game still need to have a lot of controller/accessibility settings.
