What happened to Xeno Tactic?
It had almost no trace of the original left... and while I can accept that, although it's very similar to Canyon Defence now, I can't help but notice how the turrents have been neutered. All the turrents have three attributes to upgrade which is ok... but they all start off so weak and slow, the upgrades are SO insignificant and they turn so slowly that it's nearly impossible to stop even a simple wave sometimes.
I think this game could be great with some adjustments to the power, range and speed of the turrents. Or at least the amount of money awarded so they can be upgraded faster. Plus, I hope if a third Xeno is created... you go back to allowing us to full map to drop turrets anywhere we want!
