Great game! You really nailed the metroidvania feel with teasing different paths and unreachable objects, while funneling the player towards the right objective/room. Also, your minimap is excellent and I liked that the map overlay could be viewed while traversing.
The player character is also fast, precise and very snappy. I think the movement speed is appropriate and the camera zoom level is good given her speed.
I did experience a bug where I would get teleported to the very beginning of the game, but with all my equipment and blue orbs that I'd already collected. Not really sure what happened.
In terms of improvements, I think my main issue has to do with collision. Getting close to an enemy hurt me, but the sprites seemed far enough away that I assumed I was safe. I think if either the player or enemy (or both) collision shapes were tightened a bit, it would help match the visual expectations.
Similarly, some platforms seemed reachable, in that the player character's feet reached above the platform, but I still couldn't reach it. I know I needed the double-jump to reach it, but the character's jump height seemed capable. I would say either adjust the jump height or push those platforms up at least one tile so there isn't any confusion.
Overall, really nice job!
