I ended up purchasing Awakening last night while the Presidents Sale was still going on. Glad to hear it's not short.
Green Moon is an adventure game and well worth the money. I wouldn't call it easy...but I wouldn't call it difficult either. You have tasks to do that allow you to progress in the game. Unlike most adventure games where you pick up everything that isn't nailed down, you quiickly learn that since you have a limited inventory, to simply remember where you saw things and then get those items when they are needed to complete a task or acquire an item that you'll need from someone else.
You explore a lot of different places...but the explorations are limited to a certain vicinity so you don't get lost. The puzzles are straightforward and even the arcade like shooting game was doable. The game autosaves at certain points but you learn where and when to save on your own in case you need a 'do-over."
I think I died once, foolishly,...but you go back to a save and continue on.
It's also not a short game...but not as long as most adventures you play.
