Aningan: I've read some very good reviews for To The Moon and it really intrigues me. I've added it to my wishlist and waiting for the summer sale or something. €11.70 feels a bit too much right now.
Ash360: I finished it just yesterday, I liked it, quite a lot. Not really a game though, in fact it goes further than that, I don't think it would have been worse off at all if it had no interactivity/slapped on game elements. Consider it a graphic novel when you go to buy it. I would say the story is worth it.
I agree, it feels more like having read a graphic novel or watched a movie (for about 4 hours). The story is a bit deeper and more involving than your average computer game, like a good tragicomedic movie, a bit like "Eternal Sunshine of the Spotless Mind" meeting "Inception" while also reminding a bit of "Chrono Trigger", not least for the graphics, and with some completely new themes thrown into the mix, offering enough food for thought.
But gameplay is hardly existent, it just consists of running around and pressing a single button to interact with things in order to move the story forward, with a simple push puzzle game in between 'levels', plus the controls are a bit clunky. The cinematic story-telling experience was well worth paying for, but I'd be hesitant to recommend it to someone who's looking to actually play a game.
And (thankfully) it's completely different from your average RPG maker game and contrary to the latter I think it's justified to sell this one as an original stand-alone indie *cough* "game". ;)
