Press L or A for a blue circle and both for a blue square when it reaches the bar. Press S or K for an orange circle and both for an orange square. It will be on beat with the music.
A basic idea for a rhythm game inspired by Splatoon 2's Squid Beatz 2 minigame. Recommended for use on Turbowarp. Lag will cause timing issues. Song is "Otherworldy Foe" by Keiichi Suzuki from the EarthBound soundtrack.
