Galaxy Destroyer is coming along really really well. Right now I just have a few things left to finish on it, though one of those is level design which will take some time. All the gameplay and stat saving is in place though so I'm coming pretty close to being able to release it. I figure if I keep at it everyday I should be able to have it out on the Market late next week.
My current plan is to release a lite version that only contains a few levels and then a pay version that has all the levels and randomly generated levels to play. With the nature of the game you could get a lot of playtime out of just a few levels I imagine so I think it will be a good deal.
