Makes you think, not to bad. Basic tower defense with a few tricks, nothing to complicated.the clicking interface is set up for an ipad or tablet, the buttons are way to dam big, you cant sell and repair and build fast enough because you have to scroll half way across your screen to get out of one cannon then come all the way back to click on one right next to it.overall not to bad, not worth more than 5-10, even if they fixed what they should have in the first place.

I haven't updated to Catalina or Big Sur, but every time I checked my 32 bit apps, this was the one in the list that I hated to see go. So glad that it's been updated!

You guys are behind the times! Oye! Catch up and update your games to work on the latest OSX!! What gives? If you're not going to update them, please take them down!

If you consider yourself a tower defense fan, never played a TD game, or just curious about what TD is, this is the game to get. Hell, if you like computer games even a little bit, this is an essential buy. This is a game of high quality production value, which is totally bug free, highly addictive, with a TON of replay value. One complaint: there is a sequel out, IBomber Pacific, which is just as good as the original, but with a different style of play which makes it a must buy as well. My complaint is that the sequel is only available for Mac OSX on Steam, which takes about 5 minutes to load because you have to be connected to the Steam web site to even run it. So even though i paid for it and have a copy on my MBP, if their site goes down or I can't/don't want to be online I'm out of luck. So where is the Mac App Store IBomber Pacific??? I would even double dip for that game, just to have a copy on my Mac that doesn't force me to be tied to Steam. If you haven't gotten the sequel yet, wait, stay away from Steam, in my opinion the biggest rip off in online gaming.
