*Spoiler Alert?*
While this game does have an interesting sad mood to it it feels like this "idea" would be more suited for a medium like a short movie as opposed to a game.
I mean, you don't really PLAY at all, there aren't any decisions to make. You just hold down "D" and tap "W" once in a while.
It also felt like it didn't really build up to anything, the story told isn't very deep and the way your character moves makes the cliff jump feel very undramatic.
You just keep on waddling right on off.
In summary, I thought that the mood was good but the second half of the game didn't really add much and it wasn't much of a "game".
