Wunderbar! The sound effects were perfect, the music gave a great ambiance, the controls were generally pretty smooth, LOVED the way you did the bag pickup mechanic (simple, but effective!), the projectiles were a good speed and felt good to use, the enemy health bars were a very nice touch, and I appreciated the fact you added a check to make sure we collected all the artifacts.
I only have two nitpicks to make here:
1. the hitbox for the lava was a bit awkward I found, if I started my jump too close I would catch the "edge" of it despite looking like I'm going over it just fine.
and 2. when you die, the game doesn't actually stop, you can keep running around and doing things with the "you died" message on screen.
Overall a clean and greatly fun experience, Awesome job!!
