I liked this even if it wasn't perfect,
the room transitions at first confused me... but I realise that is part of the design, though I do think it slightly detracts from the exploration aspect of being a metroidvania - I got the crown and was struggling to find the garden again and then jumped into a wall (pretty high it was a double jump) and found myself falling through the world, so you might want to check that everywhere has collisions.
There was lots to like though the graphic style was clean and appealing, the boss fight I did was fun, and I love games where picking things up makes a visible difference, and who doesn't love wearing their crown at a jaunty angle,
nice work
