So I downloaded the win game and tested it, red ring can't be moved, got it, but the fact that the bigger one can't be moved too is a bit weird at first. That litterraly rthe first thing i've done, trying to move it!
I'd remove the timer thing and just let people click play when they think they are ready, because like this damn, I find it wayyy too hard :p. But I guess with a bit of training I would be better.
The physics of the yellow liquid is nice, and it's pretty well in the theme!
