I try use physics to make a platform game, but i have problem with object collision, somethings not make a perfect collision pixel, look:

In other things, objects remain normal:

Density objects are default, world Gravity Y: 60 and Pixels to Meter: 0.1
Anyone have an idea how solve this problem?
sorry my bad english.=|
