Detailed Brief Walkthru 100% Achievements! The game tries hard to make this a Dating Sim + Puzzle game and succeeds too. Sadly the 48 puzzles are monotonous. At some point boring replaying same puzzles again and again! The basic premise is this - Chat up a girl, get into sexy discussions, Solve puzzles involving rotating pieces of a network of pipes so that you can create a pipe between 2 valves for liquid to pass through. Symbolism so strong! Refer Screenshots below.

1] Chat up. You can skip dialogues clicking arrow buttons at right bottom corner of dialogue box [can use auto clicker for long chat]. https://steamcommunity.com/sharedfiles/filedetails/?id=2903565845

You need solve puzzles in 30 seconds or 40 seconds timer with 3 stars to get for time taken to solve. Some are very easy solved in first try. Some may need couple of attempts not too hard. There are 3 modes Easy, Medium and Hard having 16 puzzles each. Maybe if you have patience you can solve same piped puzzles all fairly 2-4 hours. Randomly some meaningless anime pointless sex scene loads and frankly these scenes in these games these days are funny or pathetic.

Achievement Hunters can solve it all in 30 minutes clicking F. You can even click same in middle of chat and solve puzzle before it loads. LOL! However you still need complete clicking all chats or use autoclicker.

NOTE: If a family members has played the game fully before getting all achievements you will need play on a different non-admin user slot in windows pc to get achievements or a different device.
