The opening cutscene did a good job of showing the human take the potion to become a wizard!
The graphics were cute and served their purpose and the fireball had a decent particle effect.
Just had a few critiques. The boss AI was a bit simplistic, as it just hovered and seemed to shoot the ghosts randomly. Some change in behavior as it got lower in health would be a nice addition. Also, I believe I was able to run off-screen to the left, so you’ll want to put an invisible wall or some barrier to prevent that.
Overall, good job!
