You could have the original personality learn the skills from the dead characters through the help of the psychiater, the penalty would be that he lost part of his memory and a lower score at the end of the game. The ending could look different as well
The problem is that I'd then be effectively rewarding the player for making mistakes. It makes sense from a story point of view but diminishes the gameplay. I'm aware that it's not perfect but I value the gameplay over the story.
If anyone else sees a more elegant solution, I'm all ears. Though I do like the idea that you are not entirely the good guy in the story, but still have some valid reasons to claim that what you are doing is defendable.
I really don't have much to contribute to this thread, save perhaps to reference the game '400 years' as a potential source of influence.
Well, thanks for your reply anyway, I checked out 400 years. And while it looked rather cool and sparked some ideas for other games in me, how exactly would it serve as a reference for me?
Thanks for all of your input so far, I'm currently making more specific game design/mechanics choices and will likely post some possible puzzles in thread at some point in the future. Meanwhile I'm still open for any feedback and willing to throw things around if anyone persuades me to change something.
So far I've definitely been forced to seriously think about some aspects and make some adjustments to make them work better. Thanks a bunch for that.
