As the predecessor to Plants Vs. Zombies, this game lays a lot of the foundation for what makes that game fun, while also having its own unique identity. The premise, art, and overall tone are very fun and lighthearted, but the design of the levels can make even that feel very intense. The most frustrating part of this game is definitely some of the aliens, it feels nearly impossible to fend off certain types (psychosquids...), but the game does give you many resources to protect yourself with, and it's all about the choice in what resources you use that determines your play-style.

Past the main mode, the challenge mode to get the gold trophy is very tedious to complete unfortunately. Playing each level 8 times just wears on me personally. On the other hand, the included virtual tank option is a fantastic feature, giving the game life beyond its actual levels.

Overall, this is a very fun game, and I would recommend it, even despite its few flaws. (Also the playtime is from me leaving the virtual tank running, actually completing it doesn't take that long).
