This is without a doubt one of the most challenging games (as far as coordination goes - there is not much to write about concerning strategy or puzzle solving however) I think I have ever played. It is fun, unique and mildly frustrating - the tantalizing shiny tempted me too much, I made it up there to get it and took 50 attempts to make it back down...
5/5
get rid of the assist feature, or maybe allow users to turn it off, also, it would be nice to be able to see the whole puzzle on the grand master level
The level 7 glitch seems to occur because the mouse gets close to the member selector; when this happens, even on other levels you won't be able to move the member much less set it in a position, when this happens scroll a little further to the right and you should be able to do whatever you need to do.
has a little collision problem that happens when you are trying to pick up a blue dot that is on top of a pink dot, increasing speed would add a little more challenge on higher levels so would varying the size off the dots 3/5
