Gears logic puzzles

Great premise, works great MOST of the time. However, in many levels the cogs snap to a grid making it almost impossible to play those levels, ruining the game. That it's impossible for the game to sense which of several cogs close to one another you're trying to move, more often than not selecting the WRONG cog is also very frustrating, especially in 'gravity'-style levels!

I like the game, however there is one thing I would like fixed. The little light bulb - which I assume is for a hint? Doesn't work. I'm on Blue level 2 & I'm rather lost on how to beat this level, also I can't find a single walkthrough which would be helpful in such a situation where the "hint" doesn't work. Also, the supposed other visual options aren't there. Only wood & metal. Not that that much matters, but it would give a little to the aesthetic. Please resolve this & I'll up my rating. Ty.

An excellent challenge, a great idea and it's well implemented. Well done Sergey. The achievements say that I can buy an advert free version but I can't see where I can purchase it. Also the achievements suggest multiplayer battles, but that also doesn't appear for me in the menus. Were these features removed? Or not implemented yet?
