Awesomeness to the extreme.
I really enjoyed this game. I find defense games to be kinda boring, but I really got sucked into your's.
The graphics were quite good. The intro screen didn't impress me, (the instruction screen was awkward to read) but the gameplay makes up for it. The fire after the enemies explode looks a little like waving leaves though, lol. And, as many people have said, in the later levels, (above 40?) get ucky flashy. But it's okay, since you're going to improve that all.
I LOVE that you stuck all that music in. <3 <3 <3 And it wasn't crappy either. (at least in my opinion) And it was excellent quality.
Killer style. You took an old idea and put your own spin on it. ^.^
It was very violent, but it was kind of blocky violence. Meaning nothing like, gory, although there was a little blood.
Interactivity - nuff said.
Humor - I thought the variety of enemies was giggle worthy. Space ships and samurai; interesting mix!
Your weapons menu could be improved, but you said also that you'll fix it...hmm...that cursor thing. Yes. Okay, I IM people while I play games, so everytime there's a pause, I send a message or two. When I take my mouse out of the playing box, it flickers like crazy. I could handle it, but it was annoying, seeing as I played for several hours. (I stopped at level 60 after all the weapons. Bored and my butt hurt)
And the save feature thing. Yes, nice. I wouldn't need it, (I didn't need it) but it's a DEFINITE plus, and you also said you work on that.
OKAY! So, if this doesn't get front page, with your improvement it SHOULD. It would be an INJUSTICE NOT for you to be. Hehe. :D
Excellent game. Five and ten.
