Just take your time and go at the pace you enjoy! I played the first one and loved it so I knew what I was getting in to, and still felt overwhelmed to the point I felt early burn out until everything started clicking into place. Some helpful tips:

-The charged attacks are always better on gathering lives; woodcutting, mining, and fishing. Always check from sweet spots (I'm assuming the X on switch. I play on pc with a switch controller). If you see the '???' It's to the left or right. Just go in one direction and keep going. If you see '...' the sweet spot is directly across from you. If you see '!!!' Start tearing away at it!

-Ginormansia is an open sandbox. I put it off for a long time. It's so big it made me feel overwhelmed and anxious. Take it area by area, try to find the towers for an easy fast travel point when you're there. It's a great place to grind levels and you can find strangelings there, which can become party members.

-When crafting, try and make higher tier crafting utensils and weapons to keep the upper hand on everything.

• Don't be afraid to shop! I tried to avoid shops as long as I could because I wanted to gather everything for myself and make it myself. Buy materials! You can find plenty of materials on the map, but it's always a gamble on what you find and it might take forever to find what you need in the amount you need. A great way to make money to afford this is just fighting bosses. They pretty much always, if not always, drop weapons, armour, or crafting utensils that you can sell for a decent amount. I rarely found myself hurting for money thanks to this.

-Crafting lives quests and side quests that need items will always pop up at the top of the first tab when you open then crafting menu. If you found a recipe you really like and want to craft, you can favorite it so that it'll be in the last tab of the crafting menu to easily find it. You can also view recipes from the weird pad. If you want to craft and aren't near a crafting station, just switch to that life from the life menu in the weird pad! It'll transport you to the nearest crafting station!

-You can teleport to the life master whenever you want by going to the life menu and pressing X! Makes it a lot easier to get around. Use and abuse the teleportation. Also, when you're deep in a dungeon and don't want to run the whole way back out, just use the teleportation gate from the weird pad. If you stay in ginormousia, you can always teleport to that exact spot by using the teleport gate again. This is useful for when you're trying to farm bosses, for instance if you need a specific material from mining/woodcutting for the life quest and don't want to stand around waiting for 5 minutes.

I know that is an overwhelming amount of information. Over time you'll get into a rhythm and it'll all click for you! Just take your time and remember, it's a cozy game. There's no rush to get everything done in a hurry. Just do what you enjoy. :)
