bug fixing

this update introduces a few bug fixes for things that have been bothering me. enemy AI should work for the most part now (it was unpredictable before). i went ahead and implemented simple astar pathing algorithm so now all the enemies should blindly chase the player when the player’s in their view.

additionally, the player’s health shouldn’t change when going up and down stairs and.. well, randomly. it should accurately reflect the current / max health.
