Create melodies with movement synced to music and dance around dangerous obstacles
Embody music itself as a fluttering Flute in the Steam Next Fest demo for Inpulse, the musical 2D precision platformer, now available on PC via Steam! Collect an octave, play its note, and fling Flute into trajectories unique to each octave. Jump into the played note to launch Flute further to avoid fatal spikes, energy fields, and bottomless pits awaiting Flute’s downfall.
Play in the pocket of measured chaos with the first two Worlds hand-designed by the 20-year ROM hacking veteran behind Hackers Dreams with built-in accessibility features that make difficult series of inputs approachable to players via scrolling DDR-style inputs to help keep time. Hear (in)correct inputs as proper platforming stays in sync with an evolving, multi-genre soundtrack!
Experience the first two world’s pieces of music by breaking down each level at your own pace with the power of an instant level editor. Slow down the tempo to nail the timing, then experiment with creating an entire stage entirely your own with supported mod tools. Join the Discord to share your creations with other players and take on their levels ahead of next year’s launch featuring more than 220 hand-made levels alongside custom community content.
Upbeat jumps await in today’s demo for Inpulse on PC via Steam! Learn how to turn your keyboard or controller into a musical instrument ahead of the full launch in Q1 2027.
