Eventually, I got bored after I realized I had to switch from black to white and undo everything I had just done. As said below, a game needs more than art. It needs to actually be entertaining.
Great game, puzzled me on a few of those levels. I just hope you don't find another similar puzzle published before yours and accuse it of stealing your idea.
Well, it's annoying how sometimes the dialogues scroll too fast and I miss them. And in several chapters fighting the Aru, it got really boring because it just kept sending waves and waves of fighters that I just keep shooting down, over and over.
Good, but I think it has some problems. There should be an "undo" button for each turn and units shouldn't have random turns. Sometimes, a spider behind another spider has to go around an obstacle and can take a while to reach the other side.
