For a short while it does look like a run-of-the-mill defence game with average graphics - but having achievements in it was a great idea, it is rare in defence games AFAIK and the gold bonuses alongside are a further improvement. I liked the "Final Round" one :)
There were some small issues, like
- The poison towers being relatively weak (I finished level 3 without any).
- Some level descriptions not matching the monsters.
- Difficulty selecting a specific monster.
- Some achievements seeming nearly impossible (once fire towers level up enough the others can hardly get any kill).
- Tower actual damage not seeming to match the description (error in my favour :)
- Tower range upgrade is good but the reload one seems too expensive.

On the other hand, there were little niceties like the status icons on each monster. And none of the above is too serious. I'll have to remember this game whenever I think of passing on another one because it got a low score! :)

for the gamers who like an easy start, make good use of the achievements, after round one, you can buy and sell the normal gun towers (25 times) and you have 2600+ budget.

Hardcore mode is nice!

Maybe function speed x5?

9/10

to the gamers...I finally won the game..here are the tricks.

Build the towers from the inside curve and move to the upper part of the curve. in the beginning of the game, instead building a lot of tower, save your money to upgrade your tower distance. see the next enemy you will face and just build necessary tower you need to encounter them. shock tower works rally good. make sure you build this and make a good distance, put the frozen tower next to it. Don't forget to build all towers, but make sure the basic towers are enough.

enjoy!!!

i liked it, a bit too easy once you figured out what towers to use but other than that challanging and fun:)

maybe i pressed something wrong or i didnt understand but i tried many diffrent tactics and i still lost very fast, im normally good at td games maybe i just didnt understand something important
