Ambush is finally out of Beta - Android version coming soon.

Well, here it is - The game is finished, and available to download in its entirety. Updates include the aforemention upgrades system, which is also visual, as your sprite changes as you level up - and an extra enemy spawns when you reach a certain level, and the little ships spawn faster - This is to make the game more challenging.

I didn't go ahead with the powerup system, I felt as though the game would be too easy if I did. The now second biggest ship still gives you shield when you destroy them.

Also releasing on Android soon, but they're still reviewing one of my earlier versions.
