Super easy insane demon. I never got a chance to beat down bass back before it was buffed to an extreme that is very unfun, so this seemed like a fine substitute. One of the cleanest nine circles levels I have played in terms of fair and consistent gameplay. 30% and really the first part of the wave is probably the hardest part, but even that gets pretty consistent. Not sure how I messed up the last cube so many times but whatever. Cannot recommend this one enough, 9/10 for enjoyment!
