Heavy Rain will be the end of me

To be completely honest, this week I have been obsessed with Heavy Rain. The only break i really got was when my playstation caught the bug and stopped me for a day. As far as my interactive narrative goes, i am considering making a quiz on riddles. I could use videos from films, obviously find some questions on the internet. The only problem would be that i don't know whether i could have text entry to input an answer. If i have to narrow it down to 3 or 4 answers, it makes the whole thing a lot easier. I will think of designs that i could use, but as of yet it is still only an idea. Probably change my mind by next week.
