Glad to see you've posted something again! I admired the artwork in your movies and games, especially Dreams, and I can say the same for this game too!
I do think that there are a lot of things that you could improve here... I know it's just a demo, and you probably have more things up sleeves that you're including, but I think that there a few things that I thought could be improved *as of now*... Such as the movement of the ship; rather than letting it directly just move, you could make it accelerate instead. Also, the background music COULD use a change, but that one is largely my own preference.
Anywhos, hopefully this turns out great! Good luck on the project!
