Jijij2, it isnt a bug, glitch or any problem, click on where you type so that you can actually start typing and play the game, then type in "play" with the quotations so that the game tells you what I dont bother to say myself.
A couple things I have to say about this game: First it is a bit difficult to tell the difference of you and your enemies troops. Second the upgrade menu was a bit difficult to figure out but not impossible, you just need to take a second and actually open your eyes. Lastly, it is very repetitive as you get farther in, games get boring if there is no change in the game through every single boring level. Flawless? Not by a long shot. Bugless? As far as I saw. Boring? It does as you get farther in. I am giving it a 7/10.
