Go whole hog on the pokemon and fusion aspects. You can make the game trivial very earlier.

Hang out in a spot and enjoy the vibes, especially when it’s raining, the atmosphere can be very cozy.

Finish every dungeon in a single session once you get the option to, you’ll want to maximize your amount of time out of dungeon if you’re trying to max as many links as possible. This helps with the lack of difficulty by making resource management more engaging.

save daily, once you run out of slots try and keep like a Monday and overwrite to the next Monday in case you need to go back in hindsight. If on pc, you can get around this by backing up the save files somewhere else before overwriting.

All of that being said, the game really is at its best if you can overcome/ don’t have a completionist mindset (so ignore most of that if able).
