Like most roguelikes there is loot to collect, from shields, armor to potions there is a multitude of items to collect along the players journey that will help advancement in the game.
All slain enemies earn the player souls, which can be collected to use in increasing the players stats. This allows for the player to get a feeling of progression in that they can grow their character throughout the game.
There are only four models for enemies in the game, which is pretty low for a roguelike dungeon crawler game. Sadly that means there is not much variety in this area which can become boring after extended play sessions.
