Slow-paced
I liked the big rainbow-y blob of happiness.
As for the game, I don't think it's *that* bad considering the short amount time it was made in. The controls are too slow, both for moving around and shooting. At first I thought the firing key was bugged, before realising you have to keep it pressed in order to shoot.
The enemy projectiles were quite unnoticeable, it would be a good idea to make them stand out more. It would also have been nice if I could get feedback on if my bullets hit the boss, make it flash when hit or add a healthbar or something so I know how I'm doing.
Still it could have been a lot worse. I liked the concept and the intro movie, and the boss laser attack. I am curious to see what you could come up with given a little more time.
