Just in case I'm not the only retard, you can use the red things on the right side...

I'm not really a fan of the graphics, this concept seems like it would work better with "everyday flash game graphics" if that makes sense. The learning curve seems steep - I place 2 mills to generate some money and can't buy much else with that .. so the marbles drop right by without breaking, losing me many lives. I try placing a motor somewhere - it hits the marbles away but they don't break, I have no money for other obstacles so I lose more lives. A few tutorial levels would be nice, and since I understand the game is unfinished perhaps there's room in there somewhere? I hope to see the finished game so I could sharpen my skills at it. If I have any suggestions for you other than tutorials, it would be to make text more readable and maybe even include health bars for marbles or tell the player how many hits it takes to destroy one. Example strategies would help as well, as I can't really figure out how to break a marble to be honest! 3/5 for now as this game has potential.

Thanks for all feedback. I see that the game is found too hard. I will make easier levels. For a short demonstration of possible tactics watch http://www.youtube.com/watch?v=iUZPvWyzByI
It was not intended as a tutorial but will do until I make a better one.
The game has extraordinary and busy graphics, it was intended more as an artwork than game. If it distracts I will simplfy it. The patterns are oriental patterns, which were found to have extraordinary mathematical properties in the past few decades, therefore cought my attention. Sorry for there is no sound, will be added. Marbles get damage proportional to the velocity of collision. Infact once you set a arrangement of obstacles that works you will see that they die pretty easily.
Please state anything that you see can be improved.

a few suggestions. Make the colors of the balls change so that you can tell how much damage it takes to destroy it then give different amounts of damage based on the item hit and the speed when hit. how bout make money when a ball dies. having to spin one item to get money is arbitrary and a bit annoying. the tutorial says the square bouncers are the default but there are no square bouncers... what's up with that.

It is rather nice how you can place a mill, buy a flail/swing/pendlum and while still holding it, spin the mill like crazy for loads of cash ;P
