Previews

 * May 26th, 2004: 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. This could be a second animated mode, after the robot of course, but this teaser is the only information we have on it..
 * 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.
 * November 13th, 2015: Robert Topala entered dak2014's stream on Twitch and made Q&A. He said that a "secret project" will come out before 2.1 and he hopes that they will both come out before Christmas. He also mentioned that 2.1 won't be too big. Additionally, he said that the new features of 2.1 will be a new vehicle, a "new gameplay ball" (could mean 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..
