Bug Report: Class C
When you play the 'hit effect' for taking damage, it overrides your animation cycle, so you are 'sliding' when moving. I would expect either a new version of all of your animations in a 'hit' and 'unhit' version so that animations still play after you take damage, or using a different method to show the hit effect - for example, using the Construct 'Flash' behaviour rather than hard coding the animations.
