Thanks!! We debated on why the goblin was trying to help the hero. I think that he's trying to get him to the end so that he can defeat the evil king goblin or something, but Clay thinks that he's just a nice goblin who doesn't want to see any more adventurers fall in pits.
And yes, we had more mechanics planned. Even got pushing of barrels and boxes implemented, but didn't have time to create a level for that concept. You'd have to push them to block line of sight to the next torches.
