Previews

 * May 26th, 2015: Robert Topala makes his first mention of Update 2.1 on TouchArcade, saying "I wanted to mix up the art style a bit, keep things fresh. More craziness in 2.1!". Because of this statement, it is assumed that there will be new decorations.
 * September 22nd, 2015: Robert Topala entered Zobros' stream on twitch.tv and made a Q&A. It is confirmed that a new jump ring will be added, as well as a new anti-cheat system that allows the game to take progress (stars) from the player's stats when they use hacks.
 * September 30th, 2015: Robert Topala posts the first teaser for the update. The image shows a new four-legged gamemode, resembling a spider. . There are many speculations on what this might be, but there are no confirmations on what the new form is.
 * October 29th, 2015: Robert Topala posts the second 2.1 WIP picture on Twitter. This image shows two new icons for the cube and a new block resembling stone and lava. The first icon appears to have 3 colours: primary grey, secondary red, and an orange glow. The second icon seems to be leaving the default trail and it looks like it's a different colour from its primary and secondary colours. This could mean that you can change your trail and glow to another colour.
 * November 9th, 2015: Robert Topala replied to a question that there won't be a demon level in 2.1. He also says he will try to release 2.1 before the year ends.

Additionally, he said that the new features of 2.1 will be a new vehicle, a "new gameplay ball" (presumably a new ring, as stated in his Q&A on September 22nd), a new level (not demon) with new music by a new composer, bugfixes, and small features..
