The concept is great, the game has nice graphics and the audio fits. The theme is fit I guess, but I wasn't able to see the end so I'll stick for 4 stars on this.
I think the game suffer from readability. Too many "button" are not needed to be pressed to pass, and then you realize some had to pass the other way around, but it's hard to remember which one because it's so long and it all looks the same. So hard passage come too early in the level also.
Also died because I arrived at the loop before the screen?
