It is always hard to tell if the game is too easy or too hard as a developer. As I was afraid of that, my game is way too easy XD. Once, I stood on one enemy and he walked in a thin path so I fell and he turned over ^^'
Oh yeah I know about that, I wanted a proper knock back effect so the player would get far away from the enemy to prevent the enemy repeating. But I guess it didn't make the cut :p.
