Pure, unadulterated goodness!!
Its rare that I come across a game that I would come back to over a one year period, but your past game did so!
Thats what your newest edition will most likely do to me now...
Your original Xeno Tactic was but an experiment with the whole TD system, if im not mistaken... but now that you have seen the immense success your previous title has brought to you, you stepped it up a notch, adding many new features to the game.
The one thing that got me worked up, however, was the fact that the air units just popped out of nowhere the first time... maybe have a nametag of sorts underneath it to sort of give fair warning?
A feature I enjoyed was the ability to level up your turret by a certain field (i.e., Damage, Range, Reload) rather than leveling all fields. This gives the gamer a much more tactical standing point in the game; damage over range? It all depends...
Although I found a bug in the game where it wont allow me to sell the turrets when i wish. It really pissed me off in the deepest parts of battle when I needed an extra few dollars to stop the last guy from entering my base when I had only one life left! >:C
Other than that and some other small things, this game is perfection! The world applauds the works of Nowe Reginald!
