A lot of people would probably flame me for this but, this game is actually pretty easy. :/
All I did was build a sniper tower. Upgraded it until it had max reload and a couple of range so that it could reach almost hole map. Then waited for $4000 and built the last tower at the right, placed it bottom left near entrance. Upgrade again. Then gold tower. Upgrade. Then you build shock tower. Upgrade. You win. :/ - Try it first before you rate this comment. Really.
Aw. Is it me or are the Greenjackets OP? I finished the every stage with only Greenjacket units. I didn't even upgrade the palisades. What's up with that?
Check this. [30.21][700][30.21]
The first few seconds you'll see some sort of flower shape, then it'll create a star in the middle...
And eventually it'll form a sphere... But the cool part about it is the star. LOL
This definitely deserves a sequel... Graphics rocks. Gameplay great (but IMO needs more buttons to fiddle with like give them 4 active skills each or something) and I seriously dig the sounds! Attack! On Our Way!! nicely done...
