Nice graphics and overall in-game atmosphere. Character movement is smooth and it is pretty enjoyable just to walk around these dungeons.
The camera movement seemed a bit strange to me. I guess that is because of the dungeons being split into "rooms" and when the character transitions from one room to another, the camera readjusts itself. I would expect that the camera is either in a full control of the player for the entire map or the rooms themselves have clear borders, so me as a player would be ready for camera to move.
I liked the idea of this ring-weapon which bounces of the walls, you can create some nice plays around it like killing multiple enemies, activating something and so on. What is also cool about it is that you have to go and pick it up, after you've used it - it will motivate the player to use it wisely. I shoot it once and then could not find it anywhere :-)
Good job!
