Dude, This is Great, But...
I... Enjoyed this game for the first 30-40 Minutes. but, what i find was that the level didnt end-Wave 21 i couldnt go on anymore. After battling it out for ages, with loads of Turrets, the best tanks you can get slowly moving across the road, 1fps-5fps, and 111 factories, i found it tedious, turned it off and started watching season 3 of Scrubs. Now Seriously, its great, dont get me wrong, but the siege lasted too long. if the first level was 5 waves, 2nd level was 10 waves, maybe 10 waves for a couple more levels, then to 15waves, again for a couple levels, then to 20, maybe 50 at the last level. But, At That Point, I would suggest making a save game function. ok, its fun, but it isnt after a while, and me, with my addiction with defence games, decided to Battle it out for a while longer. but even on the 1st level i turned it off, 11 waves before it ends. it got Tedious and BORING. this is something to improve. along with the horrible 1-5fps lag. It doesnt help at all. well, i enjoyed it for a little while. so... yeah, i guess thats all i have to say. you have definatly worked hard on this, but there is much to improve :3
