Oswald is a 2D side scrolling action-adventure platformer set in a surreal spooky underground world that challenges players to triumph over simple to intense platforming puzzles by swinging on a Needle and Thread that will bend and wrap around the environment. Oswald's core gameplay is movement, you can climb up almost any wall, shoot the Needle and Thread into almost any surface to swing across giant chasms, and dash down steep corridors avoiding the various objects rushing towards you and crushing down on you. Keep on moving, never stop swinging, leaping, and climbing, or the evil shadows of the cave will overrun you!
Oswald's main foe, the dreaded chaser enemy. When it sees Oswald, it goes running straight at him.
