I like the concept and the graphics, but feedback for the player was unfortunately lacking. Better visuals for hitting things, how much things cost, where you can build stuff, etc.
Nice job tho! :D

nice one! really like the idea and the story! your animation may need some updates tho.. really nice work. Also i had a similar problem when u quit on enemy turn couldnt play the game.. it was because i didnt reseted the global script that counted the turns! 

This is a very, very cool looking and thematic game already! The way you presented story through the messages is very nice. Most concerns go towards the controls and the visual cues - turning the towers isnt obvious and the costs of those towers would be awesome to know. 

Also: Your sandstorm looks soooo much better than mine xD

Keep up the good work! Its a project worth continuing on.

really cool idea, tho it has some problems, the towers dont shoot to the left, only right, I dont think there is an indication if you dont have enough resources to build a tower? and also there is no info how much does a tower cost, the enemies also got stuck on the left side.
despite all that, I really liked the idea, it has a ton of potential, wish you luck if you decide to keep working on the game!
