Device 0101 is a game made of RPG Maker MV. You can enjoy adventures, puzzles, and battles. Risa argues with her father on her birthday and leaves the house angry. And head to a pojangmacha near the beach, the meeting place with friends who were supposed to meet on their birthdays. Risa and her friends celebrated her birthday drinking together. I don't know how long it's been since then, but Risa opens her eyes on the bed, not the pojangmacha, and the story begins. By solving various puzzles, you can open hidden places and get a key to open a blocked way. Use weapons to kill monsters that interfere with your path.
