UPBEAT

My submission for the GMTK 2025 Game Jam!

I made the whole thing live on stream — all art, code, and music

Build a beat. Control the world. Speedrun to the finish in this rhythm-based platformer where your music creates the level.

How to Play

• [A] / [D] – Move left and right

• Build a drum loop using the 16-step sequencer

• Each sound creates a platform:

Kick – Bounce platform (lasts one step)
Snare – Solid platform (lasts full loop)
Hi-hat –
  - Fewer than 8 = Zero Gravity
  - More than 8 = Double Gravity

• Use the tempo slider to speed things up or slow it down

• Reach the finish line as fast as you can!
  
  

Features

• Rhythm-based world interaction

• Three custom levels, each with a unique track

• Speedrun-friendly with reactive tempo scaling

• All original pixel art, music, and mechanics
