Pwned!!! And Owned!!! Though I have to be honest!

-GRAPHICS- 80%
As far as I like retro 2d graphics, I would adore this more if it had "3d-looking" graphics with 2d gameplay... So still, well done!

-SOUND- 60%
The Sound Effects were from gamemaker... So, not very original... Though myself having trouble finding the perfect sound effect... It's best to have a sound effect not very common to others.... Middle-class, so, huh? Right!

-GAMEPLAY- 99%
Okay, I'll admit that I don't put 100 percent, it's because, well, no one is perfect, right, so why bother? Nice, building systems, dude! Upgrade systems too... You might want to put something on the help thing... So the players could more easily orient themselves to the game... Also put in different enemies running a different speeds and toughness... Astonishing! 99? Very very nice, indeed...

-STORY- 20% to ZIP!!!
I could see no purpose of defending my base... Why would I? And Who am I? Kind of situation... So, provide a decent story... And why does anything happen here... <Heh-heh>Yeah right... Zip-lip Greenhorn!

-INTERFACE- 80%
You know, I wish I could have more defense systems like homing patriot missile launchers and stuff like that... But anyway, fully upgrading these stuff is just one-click fully leveled up to max! Also, weapons and upgrades are easily bought... So you could make an invincible stronghold in just a couple of waves... Well said, dude!

-OVERALL- 80% to 87%
Negative variables. Weapons or upgrades can be bought even with not enough money... Which makes the variable negative... Though, you were smart to not make the player purchase anything with negative variables, right? Well done, bub!

-QUESTIONS- -ANSWER THESE QUESTIONS HONESTLY, THANK YOU!-
Did you REALLY learn how to use gamemaker? If yes, then nice comprehension span!!!
Are these your original work/sprites?
Until how many waves will this game end? 50? So far I've survived until 38 then, I got bored and quit...
-I REALLY BEG YOU TO ANSWER HONESTLY, NO LIES WHATSOEVER-
