Meh, another kindergarten arithmetic game. Meh, another defense/upgrade game. Nothing new on either front. So complicated a game for having nothing beyond basic arithmetic. You know, just once, I'd like to see a math game where I'm asked to solve a differential equation or need knowledge of real statistics i.e. gaussian/poisson/binomial probability distributions or something, you know, something windows calculator couldn't just as easily do. As if I needed windows calculator to answer these questions as they are. At least for there to be skill levels in the game that did that. I'd like to play such a game just to read the comments about it, from people who have no idea how to do any of the higher levels, and they'd be all angry and rating the game down because they're stupid, that would be kind of funny. So I did the 7th grade decimals and played that turkey all the way to the end of level 16. Yay, I survived with at or near 100% health every level. That's all I get, huh, a screen that says I survived. Never needed to upgrade my castle. Bad enough that it only displays up to 9th grade, but 8th and 9th grade might as well not even be there, you don't even get to choose anything in 8 or 9. But what's really annoying is that you don't even have the problems' numbers randomly generated. I kept getting asked the same damn questions over and over again, level after level. It was usually pretty obvious which one was the right answer just by looking at the last digit if not by its approximate value, but actually getting the same EXACT questions repeatedly really sealed the deal. As for the dynamics of the defense game, they are lacking as well. The upgrades run out pretty quickly and I just end up with more and more money.
