Who am I? (Jian :D)

Waking up in a strange place, but forgetting who you are. Start your room exploration now! Maybe you will find some useful tools to bring back your memories? (The following is the game explanation, please read it after playing) You will never find out who you are... It is a loop. After the player wakes up, the player repeats the same behavior, and breath the gas that causes amnesia, and wakes up again.
