My first game

This is my First completed game. I have been messing around with game maker for a few years, but was never able to complete any thing sold. I decided to take a crack at the very first game I ever played... Missile command! I have some plans for the game to make it more modern... like an upgrading system, think ( missile speed, Max Missile upgrades, larger explosion radius, City shields, City upgrades, and even the option to rebuild destroyed cities) I may even implement a money based system, where you can buy these upgrades between rounds.  Money would be awarded for surviving cities. I would also like to have bonus rounds, that would include bomber planes, jets, and UFOs, with the chance to drop powerful upgrades.  As this is my first project.... it is ambitious for my skill set, but I hope it helps me grow.
