In "Flappy Hudin" players take control of Hudin, a mystical raven who serves Odin, the Norse god. The objective of the game is to help Hudin collect lost souls while flying through the skies of Asgard, the realm of the Norse gods.
The gameplay is similar to the popular game "Flappy Bird," where players need to tap the screen to make Hudin fly upwards, skillfully dodging logs and obstacles that appear in his path. With each soul collected, players earn points, and the challenge increases as they progress, with logs appearing at a faster pace and in more complex patterns.
