This was something of a gem.
Honestly, I usually don't review too many flash games, but I must admit, this, as small as this was, was a fan-freaking tastic game.
The art style in my opinon didn't win any awards, but that's the worst I can say, since it still had the impression and quality that someone actually paid attention to it and spent thier time actually developing it. :)
A basic defender indeed, I'm glad that it had an upgrade section, since it always made me more and more interested how quickly I could decimate those mercenaries, which, in my honest opinion, the progression of everything in those categories were well scaled and sensible.
The story may have been a bit cliche, but! It still was simply fine though, I found myself identifying with the farmers and the ending was just epic with the credits and all.
PS. The narrator was a bit pf a ham, no offense. XD
