good idea, interesting mechanic, but I found the game a little too hard specially because it's not very clear how you should play and how the main mechanic works. perhaps improving the tutorial making it interactive may help. also, the font is barely understandable. nothing that breaks the game, and this is a win. hope the developer get back to it

also, please invert the direction of the wheel to zoom. I'm used to scroll down to zoom in and the inverse to zoom out :P
