There will be no battle 'systems' however there will still be mechanics that add more depth to the game, hopefully in a way that won't hinder the gameplay as it is now.
As you may or may not have noticed, I've been slowly getting the player used to the movement system in the game. From sprinting and jumping over pitfalls, platforms and getting them to a shallow understanding of how to deal with enemies in the graveyard.

The following is probably the most "battle-like" scene the game will have. Although you won't be wielding a sword, you'll still be jumping, sprinting, avoiding and using a flashlight.
