Rhythm Quest (tuxdb.com)

Rhythm Quest is an upcoming 2-button rhythm platformer game being developed by DDRKirby(ISQ).
Jump, attack, and fly to the beat to get past challenging obstacles in this rhythm-based twist on a traditional "runner" game.
Each type of enemy requires different button sequences to defeat:

Wings offer extra mid-air jumps, while flight paths require you to hold down the jump button:

Speed zones change up the rhythm of the song:

Over 30 levels across 6 different worlds, each with their own musical themes and gameplay mechanics
"9-bit" chiptune soundtrack hand-crafted to match gameplay rhythms
Adjustable latency calibration and audio scheduling for tight and responsive gameplay
Use coins to unlock bonus stages, alternate character skins, and more extras

Rhythm Quest Demo v0.29.0 Released
