The game is not worth it. It is a worse version of Summer Memories in every aspect. I realize that isn’t fair, as SM is kind of a masterpiece, but even with my expectations low, I was disappointed.

There are 3 time periods (morning, noon, and night). The 3 main heroines are in different locations based on time of day. The fourth heroine (not related to you) only appears once you have built a fort in the forest area, and is there during morning and afternoon. Sleeping at any time will fast forward to nighttime, and sleeping at night will progress to the next day. Since you can sleep straight past the noon time period if you sleep in the morning, events that happen during noon time are tedious to get.

The oldest and youngest sisters are are in the house in the morning (in their rooms), while the middle sister is cleaning the shrine. In the afternoon, the oldest is available to cook fish in the house, the middle is still at the shrine, and the youngest is by the river. At night, your health is replenished, and you can either take a bath with the oldest or youngest, or meet the middle sister in the toilet room. Also at night, each sister is also in their rooms, and you cannot explore outside at night.

By increasing likability, you get access to more sex scenes. They all suck imo, and only the 100% likability scenes are worth it. In order of difficulty, the middle sister is easiest, followed by the oldest, the youngest, and the silver haired girl. Doing a sex scene will progress time slightly and increase likability slightly, meaning you’ll just have to do them repeatedly until new scenes are available.

Increase middle sister initially through the toilet sex scene and cleaning the shrine for $50. There is one scene in the toilet room at night, 2 at the shrine, and 2 in her room. There is a bonus scene when sleeping in her bed at 100%.

Increase oldest sister initially by cleaning the bathroom for $50, taking a bath with her at night, or buying the Q-tips key item from the shop to open up a sex scene while she is in her room. There are two bathroom scenes and 3 in her room. There is a bonus scene when sleeping in her bed at 100%.

Increase youngest sister initially by taking a bath at night, or waiting until noon to give her candy at the river (be mindful of your HP to prevent advancing time by accident). The +35 HP candy gives the most increase at 5%. Because this can only happen once a day, and you have to manage your HP up to noon, this sister takes the longest to progress. She has one scene in the toilet room in the morning, 2 in the bathroom, and 2 in her room. There is a bonus scene when sleeping in her bed at 100%.

The silver haired girl requires you to build the fort, which requires 3 items. 1st is a single rice ball. The 2nd and 3rd items are key items from the old man sitting on the box and the buff guy. Not sure what the trigger is to get their items… it might be time progression after a few days, buying an item from the store, or trading fish to the givers. You can fish at the river or the ocean after buying a fishing rod from the store.After the fort is built, the silver haired girl will be there all morning and afternoon, and you can increase favor by feeding her food (cooked fish is 10% increase), spending time with her once a day (3%), or sex scenes. She has 5 scenes and a bonus, all viewed at the fort.

Bonus is a blonde lady at the bus stop with 2 scenes. She may be on a calendar progression, but she didn’t appear for me until I unlocked the silver haired girl, so it could be either one.

Each of the 4 heroines has an ending after the 23 days is up. Never got that far because the game was very disappointing.
