Unique approach to the graphics. It would have been a very interesting code behind the constant angle that the ship has towards what is seemingly a black hole.
The game has nine stages, all of which introduce new things which add a sense of progression combined with the funds you receive from destroying enemy ships which can then be used to purchase upgrades.
There is a well thought design behind this approach, and perhaps with a bit of a more compelling back story and assets could draw people in with something as simple as a flash game.
There are some inconsistencies between art assets, and the overtly humorous approach, while fitting; does feel a bit senseless at times, such as in the shop for your ship.
I was pleased to have a sense of challenge against my skill and I look forward to seeing what you can produce next.
