windows are far too fragile.

I'm a perfectionist when it comes to arcadey games like this but "don't break any windows" really shouldn't be a challenge that exists if all windows in the game can't even withstand a small gust of wind. The hit detection is also poor on windows in game, even in cases where you visibly don't touch a window, they can still break if half a pixel of an object you're holding happens to pass by it. In my opinion this causes some levels to be annoying because of the amount of glass breaking, and in other cases even more frustrating because of how mind numbingly slow you really have to go to avoid breaking glass. This is just my opinion but glass should only really break in specific circumstances, with those being, throwing an object at/ through them. jumping at/ through them. moving at "high speeds" with an object.

if I'm moving as slow as possible, just a tiny tap from an object at a crawl, should not bust windows

I would keep glass behaviour unchanged. I think if the window challenges were more like "break less than 3 windows" than "break no windows", then you could still play fast without panicking about every window.
