I don't know why but my player "Grabs" onto the side of tiles. Its annoying!
Another bug I am encountering is when the player jumps, and hits the bottom of a block, the player can jump again performing an endless amount of jumps!
If you need an example of this, play "Links Adventure".
I have published it and you can play the game to see what I am talking about.
Its quite annoying and I am not sure what is causing it, even after looking at the behaviors in the behavior coding!
