Great job on this one!! I thought the character sprites looked fantastic, and the death animations on both the enemies and the player looked particularly polished!
For future reference, I think it would be good to lower the health of the enemies - they felt just a bit too tanky. I think it would also be a good idea to have the doors open a bit quicker once the player has finished killing all the enemies in the room, it feels like it takes a tad too long for the game to register that the player has finished off all the enemies.
Great job on the music, too! I appreciated the change of pace in the music going from the first dungeon to the second dungeon. It felt different, but they both gave off a spooky vibe!
