Welcome to Yoku's Island Express, a Metroidvania open world platformer that utilizes pinball mechanics to navigate the map. It's a novel concept that makes for a unique and enjoyable game. Like many other games of this type, no achievements are missable, and there are lots of things to do/collect around the map. Since pinball mechanics play a major role, there is some skill/luck involved with being able to make your ball go where you want, but this is a pretty casual game in that you can't actually die, so there's no penalty for making any mistakes. Let's get started.
As with many games in this genre, it's hard to provide a strict walkthrough of what to do since it's pretty much an open world. There are only a couple things I'll make note of, to keep in mind as you progress.
The first is what to do with the fruit you collect everywhere: do you save it or use it continually? My recommendation is to not bothering saving up fruit. Every time I decided to save up, I'd end up maxed out on fruit, and getting more and more fruit that was essentially wasted. Instead, I recommend spending your fruit on the access flips you'll see everywhere as you progress. I found it best to keep a minimum of 30 or 40 fruit on hand, only because you don't want to have none, and get to a point where you can't progress without unlocking a flipper, and then have to backtrack to a pinball section just to farm some fruit. Buy everything you can as you progress. There are only a couple of more expensive things, such as maps you'll find later. But those are easier to buy post game, when you'll have a huge wallet capacity for fruit and will be generally overflowing with fruit that needs somewhere to be spent.
The second thing really worth highlighting is scarabs for the "Perfectionist" achievement. Every pinball section in the game has at least one, but upwards of three, scarabs. The "Perfectionist" achievement solution has more description on what these are and how they work. I highly recommend activating every scarab you come across as you progress. In my experience, there were only two or three scarabs that weren't possible to activate, because they required an ability I hadn't obtained yet. While the scarabs you missed will be highlighted on your map, the amount of backtracking and exploration you'll need to do post game can be significantly reduced by taking the little extra time to activate each scarab as you progress.
Aside from those two things, there's nothing else to worry about as you play the game, and nothing else that needs to be prioritized or focused on. Feel free to either play through the story quests first, then come back and do side quests, or mix them up. There's no benefit to doing one before the other. I recommend focusing on story progression, and unlocking as many areas as possible with fruit. Many side quests and miscellaneous achievements require access to multiple areas. It's easier and more efficient to do all of that post game, when all areas are accessible and you have all abilities.
After completing the game, you'll assuredly have quite a bit to do. Sadly, the lack of fast travel makes this a bit slower, but ensuring you enable all beelines definitely helps significantly. The first thing you should do, if you haven't already, is to buy all the maps from the vendor in the center of the map. These will reveal everything on your map that you need. At this point, sweep through the map, mopping up any scarabs you missed, opening chests, collecting wickerlings, and completing side quests. No matter how you tackle it, this post game mop up is going to take a few hours with all the back and forth that's required to do everything. Consult specific achievement solutions for any specific achievement you need, to wrap up this completion.
Yoku's Island Express is a really fun and unique game, with great graphics and simple yet addictive gameplay. It has surprising depth and things to do for this type of game, but because of the unique gameplay design, it never feels tedious or boring. A bit of work will be required for the completion, but nothing is really difficult since you can't die or fail, and nothing is missable.
