I must have spent half an hour in the game and it was really awesome. You definitely nailed the implementation of the given theme and the whole concept of the game with daydreaming is really something new.
At the beginning I thought the music was missing and when I switched to daydreaming the music flew around my ears, what a terrific banger ^^
I liked everything about the game and had a lot of fun playing and trying it out.
I was pretty bad and it took me a while to get into the game, because the enemies were very fast in the beginning .
Maybe you could make them a bit slower in the beginning and eventually the speed will increase... that would have saved me a lot of frustration ^^
But that should not detract from the fun of the game. Really great! :)
