An extremely cool tower defense game. Vector Attack! The graphics are stunning, and the background music is also very energetic. There are a multitude of players worldwide.
There are many types of towers: some with fast speed but weak attack, others with slow speed but strong attack, group attackers, ones that slow enemies down, and more with varying attack strengths... Please refer to the instructions for details.
Each level gives hints about the type of monsters in the next level.
Tip: The range of each tower differs, as do their functions, so pay attention to their placement and how they complement each other.
It's quite difficult to succeed on your first try. I've only reached level 43.

I recommend playing in full screen mode so the text is clearer.
