My keyboard is rather expensive,
therefore i'd like to be able to use it sometimes, like when playing this game, for instance. If I'm wrong on this, let me know really quickly. I mean, as someone pointed out, this isn't supposed to be defend your castle, so dont make us click the mouse a million fucking times. At the very least, a pause button (not one requiring clicking) I like the direction you are going with the game, but needs a little rethinking.
as others have mentioned, the popup menu over each building isn't the greatest. I mean, its not the worst ever, but there's got to be a better way, maybe esc. to get out of it? anyway, that issue needs some attention.
More guns; the cost and power don't add up later when it takes so many machine gun shots to kill enemies. Oh, good variety on the enemies, btw. I'd like to see the numbers switching the guns or something too.
graphics pretty good, but it plays kind of like chess. It's great the enemies only attack straight forward, but why do you too? crazy. thanks a lot though, just had a lot to say because i enjoyed it so much, and it would take just a little to make it really great.
