Nice theme this time, brought out a lot of creativity!

Had fun working on https://ldjam.com/events/ludum-dare/41/duality

Left side is a platformer (WASD) and the right side a Shooter (mouse). Either play solo, which is hard, or co-op hotseat with a friend. The powerups on the right side affects the left side and vice versa. Collect both halves of the heart to gain a life.

Please give it a try, there's a web version. :)
