I rarely trash a game, but this one comes really close to being an exception. Many people have said this is a video game made by artists as opposed to game designers, but I must disagree. The people who made this game are neither artists nor game designers.
Gameplay-wise, there's nothing particularly good or bad going on here. The graphics are fine for the genre. The interface works. The in-game mini-puzzles are good enough. The control scheme and interface are perfectly appropriate for what the game is trying to be. That's why I gave it two stars instead of one.
The main problem is the game lacks interactivity, in that it's not about solving a mystery or becoming engaged in the world as PART OF the story. It is about bearing witness. And certainly bearing witness to a life is a worthy task, but this game fails to provide enough human interest to hook me and keep me hooked. I played for an hour or two, and all I discovered was trite, overdone, melodramatic writing.
In all fairness, I might have quit playing the moment before it would have hooked me, and if so, that's the big failure on the part of the developer: creating an engaging and meaningful game that simply takes too long to warm up. First impressions are critical, and To the Moon failed to make one on me.
