Thank you for the feedback.
I agree on the physics being a bit buggy (especially jumping in a small area), the platforms that can be destroyed are supposed to be distinguished by the fact that they are not touching any other wooden objects, and are normally hanging by chains(I was planning on having an animation of them burning away instead of just disappearing, but ran out of time). Personally, I found that the player was actually a bit too fast, although noticed that it can slow down a lot if there is lag.
