This started to happend in adventure difficulty, sometimes when I want to move my character with mouse left click button, my character starts to walk in oposite direction, this is happening more often as I progres, the issue is that you cant really do much about it, you can either die or jump to the edge of the world. At the last level, the obsidian something... when you jump off the platform, instead of teleporting you to the surface, you keep falling down and killing yourself, causing you to lose 1 life. Thank you for your time and maybe response. I couldnt find this bug anywhere else, so I hope it isnt just my game doing that.
