Characters are well drawn in a cute cartoony style they feature goggly eyes, rounded features, and are very colorful. Thankfully, the game's art and music assets are much like the rest of the game: decent stuff. Which is to say that one's enjoyment will largely depend on how much one wants to play another bitesized tower defense game. It's a lot like many other tower defense games on the market. It's a fun formula, though it doesn't feel entirely original, and that might be the game's largest flaw. That means collecting resources quickly, placing towers quickly, and zapping aliens quickly. While there are maze-like paths, as in traditional tower defense, maps are very small, and so success on any given map is less a matter of intelligently placing towers than it is of quickly placing the first few towers and then transitioning towards the action side of things. Other aspects of the game straddle this middle of the approach, as well. It tends to draw the game away from a more cerebral tower defense experience, though. It's not a bad design and can lead to frantic gameplay moments, especially when zapping an alien scientist's shield is of critical importance. This means enjoying the title is heavily dependent on whether one wants to click on resource generators 100 times over the course of a map to collect 'cogs' (the game's primary money equivalent) to defuse various alien abilities with the multi-function 'zapper', as well as place towers. At the same time, it features tapping (in the form of mouse clicking) to inject more action into the experience. Returning are twisting maze-like lanes, lending complexity to the placement of towers.
