A solid concept with an intriguing mechanic and simple but enjoyable gameplay. I can honestly say I've never seen a game like this before. I would, indeed, like to see this fleshed out into a full-length game. As it is, it's interesting; in a more complete form, it would be apt to get a fair bit of attention.
Solid four stars. Great start.
I see only one very necessary addition (besides more levels :P ) -- You NEED to make a click "GRAB" control if moving the balls are part of the puzzles (which is the impression I got, and which by the way is a good mechanic to expand the game) - "kicking" is very frustrating and not enjoyable!
Keep up the good work.
Great game, though the last hidden solution map was a little hard to see. If you gave this a plot and just a few more levels, you'd get 5-star reviews left and right. This serves well to show your potential and perhaps as a demo for a game.
I got bored very fast and I'm not really sure of the point of this game. BUT... it was unique, I can think of a million ways to fit this kind of mechanism into an adventure game, and I've already given two shit reviews today and don't want to do that again. So congratulations. This is definitely different, and that is hard to accomplish.
