This is already off to such a good start, the mechanics are good and it looks great! There's real potential here for a really really strong and emotional story!
Thank you for all the feedback! You've definitely given me a lot to work with, and I see myself going back to this video often as I tweak the game in future builds.
(I haven't figured out why yet, but some computers don't seem to like the fire shader and it gets all green and weird, so that's something I'll be addressing soon)
