Ok, first of all this is a good idea. i can see a lot of potential puzzle with this kind of mechanic. but your execution is rather poor.
There 2 button that was not listed on the game page or inside the game space and enter, and at least 1 button is important to even play the game. you can just add the (Space) next to the press start button text and it would be fine or just add all the button on the game page at least.
Then there the camera control, warping the pointer to the opposite side when it was outside of view was not exactly a bad idea it can be use to move on the small screen view with ease. but since the corrupted army was run on a time limit the warp became a big hindrance as every time i try to move my army as fast as i can it just go into the wrong direction. if you still planning to give the army a time limit this would be a mechanic i would rather change or scrap but it up to you.
still with all the problem it has, i was still enjoying it enough to at least complete it to the end. i really would like to see this idea polished a bit more.
