Saw this on Pocker Gamer http://www.pocketgamer.co.uk/r/Android/Oo/news.asp?c=56225 It's essentially the minimalist Super Hexagon version of Ring Run Circus. http://rainbowtrain.eu/
Hi! Did you try the latest update (version 1.2)? The ring change mechanic was heavily modified which makes playing it a lot easier. There are a lot of additional changes towards that goal (ej. crashing does not make you lose stars). In any case I would love to hear why it didn't work for you so we can learn and not make the same mistakes in the future! Feel free to DM me. Thanks!
