Thank you Godly_zues, shananan, ghetto and pinky for all your nice comments and critical feedback it will all be taken into account in the future.
@shannanan regarding point 1) At the end of the level you can "win" or "abandon level"
When you click abandon level it does not save your progress of that level and will return you to the menu with that particular level open, but not completed. Unless you had completed that level previously, then went back again and abandoned it. It is that way so that you can't accidentally overwrite your progress with a lower score.
2) How sensitive is your mouse/pad? You could try adjusting this a little. Does anybody else have the same problem? Either way I will bear(grrr!) this in mind!
3) The black box could be there from some ads I removed or a side effect of the Iframe that the game runs in, i'll look into it.
I hope that helps, thanks again and have a good weekend!
