More like an Alpha Tech Release than finished game
This has some promise, but it's not... What's the right word...
Exciting enough? There's no music, the viewing area is far too small for the size of the playing field and the size of the objects, there's no indication that you're about to run into a Jupiter with a gravity that you can't resist until you're on top of the thing...
It needs work, the viewing area needs to be about four times what it is now, preferably encompassing the whole playing field, there needs to be some music in the game, and some more things to make it exciting.
