A downloadable game for Windows

Context

This project was developed from July 30th to August 3rd during the 2025 GMTK Jam. Many of our ideas were only half-implemented, or unfortunately don't work, but we plan to continue development.


Gameplay

Main (intended) Features

  • You're stuck in a 8 seconds loop !
  • Survive waves of overwhelming notes enemies by shooting music with your bass
  • Every 8 seconds you rewind back in time while dropping a bomb at your last position
  • Bombs stay between loops
  • The more you kill during a loop, the higher your score rank
  • The higher your score rank is, the better are the upgrades dropped by the golden enemies ! 
  • Accumulate upgrades to boost your run !


How many loops can you survive ??
