This game is a blast to play for a couple of hours; slowly growing your city, fending off vikings and and dragons. The core gameplay loop is quite solid. Sustain, expand, defend. The problem, arises when you realise that there are a limited options of what you can build. What you see, is what you get. A balista and archer tower. Nothing more. The RTS element is rather undeveloped as well. While no one is expecting a C&C game, the fact that you cannot send your unit after another, i.e. they go to where you clicked, not who you clicked on, can be quite maddening. Is it fun? Yes, but how long is the question. At 5 dollars I'd say this is a pretty no brainer purchase; at 10? Well, not as much. If you won't feel 10 dollars, pick it up and give it a go.
