If I had to describe To the Moon in one word, it probably would be "epic" or "awesome", probably I just would say "pure-epic-awesomeness", but I don't know if it's possible to describe the game fairly even with many words and I surely won't try it... Thankfully you can focus in a review on other aspects aswell:

Story: I don't want to talk too much about the story, because I guess you better have to explore it for yourself and the game is based... well about 50% on the story. Just one hint: "I am round. Sometimes I'm light, sometimes I'm dark, sometimes I'm both. Many people want to walk on me but few ever will. What am I?" ;) Reach it or die trying and you probably finished one of the most awesome games about life, death, love and the inherent struggles mixed with some small puzzles. If I had to rate it, I would give the story 5/5 weaselpoints.^^

Graphic: It's an indiegame, and for an indiegame the graphic is wonderful, because the 16bit style! fits perfect (better then a poorly executed try of "modern" graphic) 5/5 weaselpoints.

Sound: It's hard to say, how much the game is based on the story, or on the soundtrack... I decided to split it 50/50... I really enjoyed the story and even as a "grown-up" I caught myself wiping a tear away. But the soundtrack alone is just a masterpiece. Well fitting in the story, without harsh breaks, and still escorts me even without playing the game 5/5 weaselpoints.

Length: I needed about 5h to complete my journey. Even I wish it would have last longer, it's fair for an 8€ indiegame full of awesomeness and emotions compared to some 50€ fullprice highend-graphic junk without a real story but with the same length. 5/5 weaselpoints.

Difficulty: There are no seperate settings for the difficulty but it doesn't matter. The puzzles within the story I would rate as fair and doable for everyone.

Summary: 5/5 I highly recommend this game. A real gem within the flood of indiegames! And even this all wouldn't be enough, the game includes 1 achievement and it's really simple to get!
