It's a quirky and fun, fast paced game where you have to destroy creatures called "The Flanx" because they are evil.
To defeat these Flanxers, you can sprint really fast, jump super high and can use 6 weapons, all with their own abilities.
One weapon, destroys the landscape and one weapon adds land. This makes terraforming a great part of the game.
However, it would be wrong in this case, half of the weapons are pure ♥♥♥♥ in terms of usability. Even in the levels where you get a new weapon, you can easily use another. I've, for example, never used the Stun weapon and just blasted and destroyed so much land, that I bet I would get Greenpeace or such at my back.
The campaign is also really short unless you really want a perfect score but what would that even be?
You could be finished with the first campaign in about 30 minutes to an hour. There are 2 campaigns and possible even user-made content.
Additionally, half the levels are pretty repetitive.
Does this all makes the game bad? No. It's a nice game if you want some quick action and when it's on sale, it's certainly nice to possibly buy. Just don't expect something big however.
