while working on the story/level for the prototype demo i've come to the conclusion that this kind of free time questioning is too open because it leads towards breaking my biggest rule for this, no meta-clues... as ive designed the timeline/alibis of the characters, inevitably the important characters have more to say and so the player can shoot in the dark at a day earlier and the important characters will have something to say and the unimportant characters will give the default non-answers.
im trying to think of how i should solve this....right now im testing out redesigning the level without the alibis altogether to see if it would work. if not that i need to come up with some sort of logical limit on what times you can ask about.

Too bad. I'm going to use Unity.

Why?

Good goyim.

not me, i find UE4 is the simplest

What is your game's plot?

you are a dude and you kill bad guys, great evil on the end but you have the power. You win.

Unity has better 2D support and I figure that would be the best starting place.
