Bloons Tower Defense #1 (see discussion here)was a very fun and very well done Tower Defense style game which i would consider one of the more enjoyable such games i've played, if not the most challenging.
Well here comes Bloons Tower Defense #2, with more kinds of towers and some harder difficulty modes. Yes!
I like the disposable road tacks. They sure come in handy when you need something to get a few stragglers but don't have the money to buy another tower. I beat it on easy with about 11 lives left. I forgot to get a screengrab though. I mostly used tacks, but had had three cannons and two freeze towers to take out the lead balloons. I got a boomerang monkey toward the end, too. On the last level I sold a bunch of my tacks and my boomerang monkey to buy a supermonkey. I think I probably could have spent the money on the road tacks and won with just those.
$3600 for the super monkey, $25 for the road tacks. If I spent the $3600 on road tacks, that's 144 road tacks. Each tack can pop 10 balloons before it goes away. That's 1,440 balloons.
