We completed the game and chose the first ending. We skipped one memory, though. The level with the open space took some time. Maybe it would be a good idea to have a counter for the memories? It might spoil the exploration and surprise a bit, but on the other hand, it helps to see your progress if you are stuck.
The art style is cool. All these art pieces make an intriguing story.
PS: When you have a marked trail you are supposed to follow, you instantly want to ramble around instead :D
