Thanks for checking it out! I wish I had mapped out the intersection between the music and the level design more clearly before fleshing them out. The last two levels are the only ones I'd consider "real" levels where they have intentional choices and crafted mini-puzzles of figuring out the best route to take. Though, the last level only got there by me restarting over and over and over and building each sequence one or two beats at a time. If I had taken a larger view of the whole game, I could have figured a way to programmatically created levels from looking at a MIDI file, mapping the beats, converting those into rotation and track data, yada yada... would have taken more upfront to get that system down, but would have made for smoother level creation and more engaging levels.
Also wished I could have playtested with others more. I'm sure the controls are unintuitive to others and the game doesn't do a great job of leading you along. The difficulty might be a bit on the harsh side too, I regret not adding a custom difficulty slider so everyone could enjoy the levels at their own chosen level.
