even though the game freezes my computer if i get more than about 25 turrets at once, i give it a 5. excellent gameplay, excellent upgrade system, good variety of turrets, and cool levels.
AAAAAAAAAAAH! the least you could do to prevent accidents from happening is make it say "are you sure you want to go back to the menu" when you click the menu button. and much of the time, when i click on "erase" it draws a diagonal line across the screen, so i have to click erase again. and again.
argh. it's glitchy. got to level "fizzle" and it just froze. and also, i keep dying randomly. i'll be standing on a line, and waiting, and i'll just die out of nowhere.
ehhh, its okay. but not great. first time i played the game lasted about half an hour, and it just kept going back and forth. its really luck of the draw after a certain point.
