Sure, you could play a tower defense game where you place towers in fixed positions around a track; and sure, you could play one where you can freely place them to form mazes; but have you played one where the towers create a vertical obstacle for monsters to bypass? BoBo Brother Defence by Joybean is all about stacking the so-called BoBo's on top of each other to make use of their individual abilities and stop the incoming waves of enemies.

The game gives players a 5x6 grid to drag and stack towers in to place, creating a giant obstacle that hopefully delays the rolling enemies long enough to take them all out. Cash is earned and spent on building new towers and upgrades, however if you should want to change the formation of your towers you'll need to sell the blocks from the top-down, so planning your final configuration is a must.

The simple cartoonish visuals are fun, but fairly boring as players are treated to the same enemies and attack animations regardless of the blocks used. Their expressions are different, but this doesn't lend them much in the way of individual characterization. Also, the gameplay is severely limited and even when using a grid full of the game's most powerful final upgrades you'll struggle to break beyond a certain point.

This is in part due to the frustratingly limited AI that focuses on units despite others quickly rolling past, refusing to apply the slowing effect on those that need it. BoBo Brother Defence is a quirky TD title, but it only provides a brief challenge before becoming repetitive and impossible to complete.
