Rating Curve

I always liked this level as a kid and I ended up beating this a few years ago as a second hardest. The visuals aren't anything amazing, just average 1.9 designs, but the gameplay was honestly solid minus the dual at around 60% which was a bit janky. Not sure if I would recommend this since I feel like I enjoyed this more than most people, but you can still give it a shot. If you don't like this, then don't try Entwined Room.

The decoration in Extinction didn't exactly age amazingly, but it's not anything awful either. I really enjoyed this level when I first beat it years ago. I thought the gameplay was fair even with the somewhat tight wave gaps. It felt more challenging and rewarding for an easy demon at the time which I really liked. Solid level overall.

Unique level for its time. The classic Nine Circles effect is something I've always admired and even though it led to one of the most overdone trends in the game, the original stood out amongst other levels as something original and impressive for its time. The gameplay isn't anything noteworthy but still offers a nice challenge for those looking to improve their wave skills. I would still recommend Nine Circles for that as well as the fact that I think everyone should attempt to beat levels that have had such major impacts on the game such as this.
