This famously difficult 2D platformer is a love letter to the golden age of arcade gaming. You control a small, square protagonist who lacks any traditional weapons, relying entirely on wall jumps and precise air control to survive. The levels are filled with spinning saw blades, laser beams, and pits of needles that result in instant death. Every time you finish a stage, you are treated to a simultaneous replay of every single failed attempt you made, creating a chaotic swarm of spirits on the screen.
