Really like the graphics, the sounds are nice too. Really smooth as well.
I had to read your instructions a few times before i realised what I had to do though. The way the fireworks are positioned above the rocket to begin with was what threw me.
That was some powerful fireworks :)
Haha i was trying to put the fireworks underneith the the ship instead of on to it (which still pushes the thing funnily). You could possibly force the player to attach the rockets to the ship - and if they didnt they wont fire. (I wont edit out my stupidness, sometimes its valuable to see how people misinterpret instructions)
Playing it properly - its pretty fun, well done.
