The platforms were laid out thoughtfully, I reached the level where left shift was introduced, but I fell straight down from the stone stairs, maybe I didn't understand something. The bg music was nice however it kept shifting towards my left channel, I guess the listener was on the player and the source at the start of the level, could remedy that or leave in as a artistic choice. The music also cut off abruptly at times. I could see where thought went into the levels, I wish you well on your game dev journey.
