INTERVAL is a minimalist platformer where the world changes every pulse. Observe the rhythm as platforms appear and disappear, spikes alternate between active and inactive, fragile platforms collapse beneath your feet, and keys unlock the exit across 25 handcrafted levels.

Every level is built around a single core mechanic, encouraging observation, timing, and thoughtful movement as the challenges gradually become more complex.
