1) in other indie games their lighting effects are very well delivered, do you have a technique in mind to rival them? for instance legend of grimrock is from a small indie team who have very good graphics.and have great lighting effex.
2) as you mention lights attached to entities in the video of kickstarter, do you still intend to do this? as can be a big player in many peoples eyes, like throwing fireballs, flame throwers, swinging lights etc. flashlight is a great addition and i expect was to keep some quiet, but i want to know if you have a plan?
3) do you ever worry you can't achieve what you have said you can? in other words how confident are you on getting all you said to the pledgers, delivered?
in fairness this is a beta and you are delivering but, as it is an interview some very indie questions need to be given.
an unquenchable thirst for knowledge of game creation!!!
