Pd: Recently I have found that when you obtain the green vinyl when you go in the platforms of the top of the screen I mentioned in the previous post, and you try to return to the previous screen (with the water coming from the pipes), you can't see the bottom platforms. I think it could be another possible bug too.

Pd2: I think that I have located another bug. When you exit from the door at the bottom of this screen and fall in the hole which is next to it, you come stuck in the hole position like you can see in this image (other people can check that the zone where my character is stuck is where they can found the hole which I was talking about).
