I already had experience with such an event, so I did not waste time just like that (although sometimes it happened). This game is about a cube that rotates on a circular axis. You need to sometimes press the left mouse button to the cube began to spin in the opposite direction. Actually this is all you can do in this rhythm game. You are not so easy management will need to pass 3 levels. Each is more complex than the other. You can start at any level. In the settings you can specify what color your cube will have, the background color of the menu, and also turn off the sound when you want the cube to start spinning in the opposite direction. The game has harmonization. Harmonization is a kind of coincidence of sounds with the music that plays in the background. In each level there are different mechanics of new obstacles (in the first level there are horizontal walls, in the second there are vertical walls, and in the third in General walls begin to move). On fact planned first 4 level, but time I have not so many, as it turned out. In General, the game play is actually good, but requires completions, as at the end of the levels of music with harmonization is not very combined. I hope you will play and you will like it :)
I have no idea what "circles" you are talking about.
Clicking seems to just change the way the cube behaves in a random way.
But man, this is HARD! I managed to get a hold of first level to reach quite far. Second level was harder, but still managed to progres a little. But level 3? Are you as a creator seriously able to beat even first obstacle? If so, kudos to you.
Overall this is quite a fun game, with some difficulty adjustments this is something I could have on my phone for boring moments.
as @shad said, i would have a video of you beating the game x)
That said, i haven't seen the time passing by, so it's a good game if you want to pass time. But yeah, controls are confusing at first and it's really hard to correct a mistake you make. it's often better to just die and restart the level (but eh, never went part the first lvl so I don't think I can be a good judge ^^)
