Loved it!
The visuals are very nice and the animations and VFX are simply great, especially the sword combo. It all moves like you expect it to. I missed some SFX like one for jumping, activating a checkpoint or when the flying squids attacks, but those that were present were on point. The music was nice as well.
I liked the descriptions in the inventory for the items you start with, it was a nice touch and a good way to tell you more about your character.
I had some frustrations with platforming as I thought many platforms were too small. Dashing would often overshoot them. For the glowing mushrooms I would need to carefully place the camera above my head to make sure I would actually land on it. Also, I often missed the timing for the bounce. At some point I had to restart the game because I jumped toward the checkpoint followed by rocks but I didn't have the bombs yet. For the life of me I couldn't make it back. (But it was okay, I could quickly go back to that point.)
I found the punch a bit underwhelming compared to the sword. It took too long to charge and getting hit by an enemy wouldn't entirely cancel it, which was weird. But the final puzzle involving sending the bomb across was great and really hit that "ha-ha!" feeling you want in a metroidvania. Then the pillar came down on me and crushed me, which was also very funny.
Great job with this one, I really enjoyed my time with it!
