Flash crack

This is incredibly adictive, bacause it offers a new look on the good old tower defence games, but unlike them it doesen't get boring in 15 minutes. Also judging by the acheivenemt, the scroll and the dragon water I smell a sequel

beautiful & challenging

well, actually everything has been said yet. ^^ i can recommend the points my previous speakers just have expressed.

i played for .. uhhh ... about 7 hours. reached level 18 and got almost every upgrade yet.
so ... it is true that the game is very challenging - and thats not for everyone. it is also true that the game gets boring over time, because your only goal will be hunting after lots of gold to get the expensive upgrades.

apart from that, the graphics are just beautiful made. and the music matches perfectly to the whole content. furthermore it's a cool idea to invert the system of classic "tower defense" into "tower attack".
for those who like that kind of stategy games, this one probably is a MUST PLAY. i really enjoyed it.

the enumerated deficits are well compensatet. therefore 5 points and 9 stars!

Good ideas, but not for everyone

I liked the basic concept and the castle extension idea. The units have intelligent properties that make you rethink your strategy a lot. The order in which you send your units in affects the outcome of a battle significantly.
Despite this one of the design choices or more pushes this game over mere challenge and into straight frustration. Maybe it's the cost of upgrades, or perhaps it's the perpetual increase of spell cost. Maybe it's both things. It feels like this game only allows you to play in hard mode, which may entertain some players, but will push many others away, forcing them to grind the same levels over and over until they can't take it anymore.

For now this game contains too much grind and too little involvement for it to be worth the time it takes to complete it.

First Good Reverse Tower Defense

Congratulations! This is the first fun, challenging, and well-balanced reverse tower defense game I've ever played. There are just a few balance issues that if fixed could make it even better. First, as fast as I can tell the turtle is never worth building. Because a fully-upgraded raider can take 1200 damage and a fully-upgraded turtle 2000, if you can get the raider through just one round you're better off with the additional point since damage scales 10% per round. Fully-upgraded turtles should have about health, or at least some damage reduction. Second, the cleansers are never worth building. You're always better off using an elemental, then just using the extra mana from it to stun the tower or quake it. Just one elemental can thus protect the whole army, as opposed to at least 2 cleansers. To balance this, cleansers need to have a much larger effective range. If you fixed these problems, you could make the game much more challenging in the later levels and require a more complex strategy than just effective spell use.

Good concept, poor execution.

I simply feel that this game could have been something good. The upgrade system is down right disgusting. I find myself grinding on lower level cities for money to buy upgrades, which makes the game SEEM longer. I've made it to like level 8 or whatever and have 0 interest in continuing forward. The upgrades are far too expensive and give very little upgrade. It's like "ok buy the units first, grind money and buy the army size upgrade to max, then do whatever". That's my guide to this game. Very very very boring game once you actually start playing it. Furthermore I hate the fact that your units do not reset each wave. I had the giant turtle walk in with oh say, 25% hp or much less probably onto wave like 3(leading a group of 4, this was an earlier level). he had a healing priest and goblin tailing him. (The other goblin died that was in front of my turtle). I spam the spells but they become far too expensive to rely upon to "shut down" the defense towers. I find myself simply looking at another game that substitutes "grind playtime" for actual playtime. If it wasn't for the level of grinding you need to do, everyone would slam this game for being too short I'm sure. Sorry but you get an honest 4/10 and a 2/5.
