I enjoyed this game, and thought it was well developed. One nitpick that I would love to see the developer fix, is the inability to use the numpad. As a lefty, AND playing on a laptop, I found it most unweilding to have to use the top row number keys.
While there are certainly lots to enjoy about this game, certain problems either distract or even disable this game at times. Many times I would get black object instead of actual tower, and I believe it happens when you attempt to place a tower when there is a difference between the price SHOWN verses the price after it's raised and the amount you have available falls in between. And the big problem for me is that the flying creeps are RANDOMLY flying to various finish location in the "Florida - International Drive" map, including from the top right to the top middle, which gives you about 2 seconds to shoot them down, and it's a no tower location...
So, lots of problems that need to be resolved...
Crowflight, thank you indeed... Your strategy worked perfectly for me the first time I tried it. Not sure why it worked so much better than what I was doing, but it did. Thank you for preventing me from a migraine headache in frustration.
The lack of powerups (other than the split dual cannon thing) made this a three out of five star in my vote. Good graphics, nice concept, but needs work to be a "quality" game. Also, the lack of a pause button is inexcusable.
If you have defeated Apocalypse level, please post how you did it. I have played this level about 20 times, and the random factor makes it impossible to figure out what will work. I have done the EXACT same set up in the same order, and it varies from dying in 5 minutes to dying in 30.
Developer, please remove the "fade away" aspect of the tower rows, as it does nothing but annoy the heck out of people. And, VERY small nitpick, you have Apocalypse level at the start menu with a different color background than the other three levels. You should make it the same color.
Four stars out of Five from me, for excellent graphics and game play, with a problem of too short for the first three levels, and too inconsistent in Apocalypse level.

Hi! There's a control key config in the options. You can set Numpad keys there!
