Plays like an Anomaly clone so I guess it took inspiration from that. But it's a lot more casual and because of this casual players aren't overwhelmed with the features like in Anomaly. I like also the Upgradesystem because this gives the game more tactical depth since you have to decide which upgrade will you need in the next level.
The only reason why I give you only 4 stars is, well, it's basically Anomaly, not only inspired but it, it is in its core Anomaly. There are some differences (like the upgrade system) and that's why I give you 4 Stars.
