Oh my, a fellow Godot user! And it supports gamepad play too, which is definitely a huge plus for me.
Graphics wise it's cute and childish -- in a good way. Not exactly polished, but I love it.
The biggest weakness is perhaps the gameplay... When it's easy, it's too easy as in I just need to spam attack. When it's hard, the gameplay mostly consists of me running around and attacking the enemy -- which sometimes don't work when the space is cramped and I have to resort to tanking. Furthermore, the boss can be stunlocked. Some refinement of the gameplay is definitely needed.
Very good submission. Definitely will be put in my let's play video of some submissions to this jam ^^
