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
