Circulatum is a 2.0 Medium Demon created by Ellixium and Xaverious.
The level uses the Nine Circles style, but in its 2.0 variant. The first part of the level is hell-themed, with lots of details, while the wave part resembles the style of The RealistiK, but with a blood red colour scheme, flashing lasers and shadowed borders. A low-detail mode is available to reduce any lag. The level is considered an easy demon.
The level starts with a simple but somehow annoying cube section with some hard timings and a partly overshadowed screen￼. Next, the player enters a simple ship sequence with size portals along the way and then to a still simple wave with the same layout of the ship. After a straightforward ball with jump rings, the player enters another ship sequence which is tighter and harder with more spikes and gravity switches. After that, the player goes to a sequence that may be entirely inspired by Ultimate Circles: a robot segment like the transition cube segment in Nine Circles, a simple ball segment, a second robot that goes nearly auto to the drop with a corridor of gravity portals. The drop starts pretty late in the level (59%) and the wave is introduced. It's not too difficult but the custom background can easily throw off the player. The wave goes briefly in ship mode in the middle. Then, the level ends with the names of the creators and with the written "obj limit."
