A pretty simple-looking tower defense game, but it's much more challenging than I expected. The mechanics are simple to understand enough.
Players place towers to eliminate opponents before they can reach the base, as well as some obstacles to slow down the enemies. As usual, players can upgrade their towers too, and this makes them a lot stronger. There are eight types of towers so far, and while the variety ain't that big, I think keeping it that much is great as having too much variety can be bad for a challenging game such as this.
I have to be honest though, this game is HARD. A lot more challenging than other tower defense games. Strategy is more important, including tower placement, as well as where players place their obstacles.
Overall, it's an above-average tower defense game that is tougher than usual. Sometimes, a lot tougher than usual. A must for any fan of tower defense games.
