The game has got really cool visuals and atmosphere. It reminds me of older titles like Diablo and Dungeon Siege.
As far as the gameplay is concerned, there is not a lot to do since the skeletons are killed easily and they don't drop anything. Spawning dozens of them further down in the dungeon does not make the game more challenging. The boss was a welcome addition, but as soon I got him locked in a stun loop, I also got the upper hand quite easily.
If you keep improving the game, there is potential to make a nice action-rpg with retro vibes. The spinning mechanic could have a cooldown effect to make it a special ability alongside a more common type of attack.
