Helix was here ;)

Level is ok, but I would try to avoid putting tons of midspins and tiles inside / overlapping each other, this makes the level extremely hard and annoying to play for the first time (sightread) as you often can't tell ahead of time what you need to do and either have to know the song well already or just figure it out after losing a couple times to it (example of this happening is about a quarter though the song on around beat 100 or so practice mode tells me)
