i was just looking around on this site called the cutting room floor: http://tcrf.net/The_Cutting_Room_Floor
and it turns out there actually is a working password for this game, http://tcrf.net/Nightmare_Circus
i know i've tried in the past to go through all the possible passwords a few times off and on but i never found anything till i came across this page. its not much as it only opens a scene select option in the somewhat confusing debug/level select menus but at least 1 mystery has been solved in that game...never did figure out what that message you see after the final boss could mean or be referring to though o.O could be anything or nothing, i dunno
oo even more codes from a youtube comment here: http://www.youtube.com/watch?v=DiNd3F52i7g
1. BLOODTHIRSTY
2. ALLAVAILABLE
3. SPIRITSHADOW
4. INFINITEIPSI
5. LITTLEPUPPET
6. FASHIONSENSE
7. THELASTLAUGH
8. TOTALCONTROL
9. INDIAN SWAMP
thats a lot more than i expected.
