decent, needs a few changes
it was ok in my part, it lagged a little, and for a friend, it didn't load past level 8, I beat it after letting it sit there for about 2 hours once I got my towers made and all upgraded to at least level 4, after I racked up some credits, I started to upgrade them to level 5, once that happened I just basically left it alone for a bit and it was way too easy, also, there's a slight bug in it, you can actually upgrade the towers past level 5 if you click really fast from level 1 (making sure you have credits to get to at least level 4) and clicking about 10 times, it'll put them to level 6+ and they suck ass at that level, they're worse than level 4 towers in all means except attack, with 80 range, 0 speed, 325 attack, at least that's what it was most of the time, occasionally, I saw some with 300 range, -10 speed, 600 damage, so, fix the bugs, make it a bit more interesting, and for the love of sanity, REMOVE THE DAMNED MUSIC OR PUT A BUTTON TO SHUT IT OFF!!!!
