It's good, but it could have been so much better
It's a really good idea, with a slightly pretentious story and dull gameplay.
First of all, the idea is sound; flying around a dream-like world, searching for objects, trying to make it back to the anchor point... I get that. It's a nice thought. Simple but elegant, not too much can go wrong.
The story was... well, not brilliant. Just a little too pretentious for my tastes, and I didn't enjoy reading it as much as I'd hoped. It was a good idea to put these insights in, but there were too few for me to really feel enveloped in the storyline. Simply put, I really didn't care for the character I was playing, and if you're going to make a game like this, that's kinda essential.
The gameplay is dull, if not effective. It was challenging, frustrating in parts, but once you had mastered the controls it was fun to play. But it was the same thing, over and over, without variation. By level 4 I'd had quite enough of it. I thought the level styles would change, but the objective remained the same. I'd have preferred level specific goals, with different elements to keep things interesting; for instance, on the planetarium level, how about spotting all the stars instead of having to navigate through narrow passages for the umpteenth time. The design just felt a little lazy, with no rhyme nor reason to why you had to fly back through the passages.
I'd love to see some kind of spiritual sequel with some more innovation. In flash games, the gameplay is king - let the story come second if you have to.
