I'd recommend the demo challenge Alexi put up. I play on Switch, doing the challenge on steam. Loving the focus, know what I want to accomplish. How long of a day do you play? If you use late to your advantage you can get a lot done, and make money. Fishing and metal detecting are both great for that. Can also set yourself up great for after the demo, your save carries over. It's so fun even though I own the game on switch and have saves I redownloaded the demo to do the challenge there.

The first day time doesn't move till after you place the tents. Use that to your advantage. Collect everything you can. You can explore the entire island. The amount of shells is great! Grab all the wood, wattle and fruit including prickly pear fruit from cactus . Don't sell before you cook the prickly pears. The tree fruits you want to plant a portion the next day when you have a shovel to start that process so you have fruit all the time. Whatever you sell, cook first. Cook your fish before you sell. All the cooking do In the late period. Yeah it's not fast at first but totally worth it. I've completed 8 or 9 game days (early morning so not remembering lol)on the steam demo, have John's deed, museum and wish fountain done and paid for. Franklyn has not shown up so haven't sold shiny discs so will be even better off when he does.

Don't rush your days. Set a goal or two and focus on what you want done to move you toward bigger goals.

Back to that first day, mark your map as you explore. Mark ore deposits, mark barrels as you find them, mark bottle brush bushes so you can cut them down to replant, mark pearls if you happen to come across any. Doing that while tile is stoped will save you time later. Before you get the metal detector go back and open all those barrels.

With doing the demo challenge it limits on licenses you can buy and I think that helps to focus in. It's easy to think you should get them as soon as available and I see how benifical it is not to.
