Even for 2016, this is just too uninspired in every way - which makes me notice that it's rather short too. I usually don't talk about the time to beat, mainly because it purely views games as a product with longer = better, or the terrible phrase 'value for your money'. But in this case, you're paying about 2€ for 2 hours of not-really-entertainment. Maybe if it's in a bundle and you don't wanna play Hexcells while watching a video?

One of many zombie defense games, Zombo Buster Rising is probably one of the cleanest-looking and easy to understand. Regardless, it suffers tedium as much as other games similar to it, and doesn't really do anything creative from beginning to end.

100%'ing the game is fairly easy, but also tedious and frankly mind-numbing. Don't expect anything unique if you play this.
