『Class 1-A』 is a “real escape-style mystery-solving walking simulator game” where you solve puzzles within a short 15-minute timeframe to reach Class 1-A. Amidst the chaotic state of the world, I created this work based on my feelings after seeing various opinions flying around on social media. The theme is 【Continuing to Doubt】. There is no single correct interpretation of the worldview. Please play it yourself and enjoy this work with your own interpretation. The stage for ‘Doubt’ is ‘School’: You become ‘I’ and start in a classroom called ‘Class 1-G’ where you awaken. It seems that if you go to ‘Class 1-A’, you will understand the ‘Reason’. However, it seems you won't reach Class A so easily. To reach Class 1-A: Solve the mysteries of ‘Class 1-B to F’ within 15 minutes. Use the ‘chairs’ to solve the puzzles. Nothing but the chairs may be used. Avoid colliding with students. ‘Trouble’ will occur, reducing your time limit. What conclusion awaits in Class 1-A? Enjoy the real escape-style mystery of ‘Class 1-A’. Play Time 15 to 90 minutes Video Streaming To be released at a later date.
