I really like the idea of multiple ships, and moving between them - each with their own strengths and weaknesses, along with a unique character and colorful design. I feel the overall moment's abit too giddy, though. Not as response as I'd like - or maybe too response the way they glide almost too smoothly. In contrast, the game pace feels a bit slow, even if the enemies get more and more challenging, and eventually arduously so. I think the calm music contributes to the lack of urgency, though it's not bad music per say. It's tense, and spacey, but doesn't really push you on.
I also wish you knew from the start how long the game was. How many phases there are. A level selection (once you've unlocked the respective levels) would be nice too. I like the art, and sound, and idea of it all: it's fun to play too, but does feel a bit imbalanced, with a bit fast difficulty curve... unless you try to play through without points, in which case it's instead reaaaaally slow. At first. Nevertheless a great game, polished and creative, but could be perfected further.
