This is Tempest
That's all, and I was never a fan of that game.
Reviews for "Galaxy Defense"
Sorry but...
Nothing new,
Nothing original,
I've heard this music before, and you left no credits for it,
wth is this doing on TOWERdefense.com?
No upgrades
No "nice" powerups
...Why dont people try to make NEW games? stop recycling the same thing, if we want it we'll search for an older version... >.>
