Before playing BIT. TRIP FLUX, I didn’t know if there was some narrative history behind the dark rectangular shape as the silent level cut scenes suggest, so when I booted up the game to play a simple rhythm game, I was surprised to find a significant effort in creating a multi-sensory experience that challenges the player in unique ways. The specific things that get challenged most rigorously seem to be the wrists and the eyes, which for players of reflex and other visual rhythm games makes this game probably pretty easy. For me, however, it was three days of harrowing light-juggling exercises and sore wrists. This was only a minor and temporary grievance, as the game provides clever ways for the player to get better.
