Write HTML, CSS and JavaScript for a fun and unique game where a user must enter a password according to [a set of] rule(s) which change(s) every level. As the user progresses the rules get increasingly absurd and difficult to meet. At certain levels (milestones), the password box will gain [a] new feature(s) that must be used to meet rules in the future. Gradually the game should get incredibly difficult and insane. Rules could include things like maths, graphs, chess, etc. Include a minimum of 30 levels in your output. Each level should be entirely unique and creative.
