I have an idea, and it's about APTX. There will be two game mode: one is trivia and second one is adventure. It's more of interactive game require less animation, because they all are questions based on your answer to move the game forward. The questions are basically based on characters, their traits or favorite we have known from DC.This game need at least 15-20 questions form for each mode. If you reach to level 5, you get APTX's cure and your form become 'Shinichi'. later there's a bonus game, it consist of many letters and see how many words you can find in wordsearch puzzles. It will continue in next game and this last two rounds' time and Shinichi turn back Conan. The points are based on answers, and how fast you are typing questions, finding words in wordsearch.
Adventure form is emphasize on speed. You can think of many games relate to speed, for example: keyboard typing. You have type a summary of deduction to catch the culprit, then word animation appear: case closed, cracked. There are many type of games can relate to speed, running after murderer with two buttons of arrow direction. and money collection after each round finished! Coins are used to buy Agasa's gadgets to fulfill each round to unlock new level. Before each stage is finished, you get APTX's cure, solve word search and one small scene from Detective Conan pop up for next challenge, and next is to piece the jigsaw puzzle to solve the challenge before move on to next stage. You turn back into Conan!
ADDED:
I also thought of second game, it's based on money deal.
It's a bit like Deal or no deal, what you do is to click the case and answer the questions based on movies. Hint maybe provided but few dollars will be deducted. If got the answer right, the money in case is yours. If it's wrong, you get zero and the game continued. When four lives are used up, you get previous amount earlier adding to your account. If got all questions right, you get bonus prize. If you decided to give up recent hard question, you get the recent prize from the case and get your answer check. Detective mystery can be included in, it will provide the question who done it along with answer.
