From not-so-retro Funkyland's cute sweet shop and their Mr. Frog you escape to Miyabure's room. Watercolor art and music create pleasant atmosphere here, and the place is peaceful enough to concentrate on puzzles. Hottategoya's room is very peaceful too - seems you are imprisoned in solitary confinement. After successful prison break you get stuck in Naoki Nakashima's bathroom without any special equipment - toothbrushes and a soap are your tools!
Have a good time and enjoy!
