Wow, this pixel art looks really good. I'm surprised you're a beginner.
I like the different ways the abilities click. I found myself wanting to try them out. They're very satisfying to use.
I found the game a bit difficult in places. I feel like the normal attacks aren't too effective at taking out the monsters, compared to the cooldowns. And no invincibility frames means you die easily. I like that you can pick up the hearts off the ground though.
The music is nice, but I found it a bit loud and needed to turn it down during the game.
