Thanks a lot for your comment :)
Glad you liked the idea although it lacked polish in many cornes. There are quite a lot of bugs and shoddy design pieces - although the disappearing walls in the office are actually an anomaly ;).
About level 9 : basically you progress every time you guess correctly if there is an anomaly/oddity or not. You go back to level 0 if you fail. Level 9 is just the random level I decided a player wins. Alternativly you can win by finding all oddities.
I guess the first step in polishing would be to rebuild the office as that was a pretty rushed process and resulted in some pretty messy visuals in some places :)
Thanks again for your encouraging feedback!
