Here's another entry into the list of GAPP genres that use Kanji clues: Atosaki Maze / 後先メイズ! I didn't check if this puzzle is still unique if you got the characters the wrong way around, but feel free to try (not recommended).

Rules: Draw an orthogonal path through centers of cells from S (start) to G (goal) that passes through every cell. In each region, the cell marked 先 (before) must be passed before the cell marked 後 (after).

Interface tip: The linedir mode is pre-selected in the interface, which you can use to pencil mark path direction. This will help a lot when spotting certain steps in the puzzle!

Finish the puzzle in 3:00 or less for a Speedy Sloth 🦥!
Finish the puzzle in 6:00 or less for a Quick Crab 🦀!
Finish with any time at all for a 先゛(??) 🐦!
