Majesco has unveiled a new DS game titled Marker Man Adventures.
It'll feature 150 "scrolling world puzzles" that you'll solve by drawing geometric shapes such as lines, circles, boxes, triangles and pivot points.
Marker Man, you see, is on a quest to rescue his friend Doodle Dog, and it's your job to help out. The game features underwater, outer space and ice environments, and each level will have hidden areas to explore.
Marker Man Adventures is out in Europe early next year.
