pixelated platformer where you play as a witch

[Mr. Meowface]

I can't for the life of me remember the name of this game I used to play in my childhood, maybe someone here can

-it was a 2d platformer with pixelated graphics
-you played as a little witch (i think you had a purple hat)
-you would go around and collect orbs or crystals or something that would unlock more spells and upgrade things like health and jump height
-there were bosses that would give you keys or something to access the next area
-there was a map that was filled out as you explored
-the whole world was laid out kind of like a cave system
-i think there was an achievement system
-there wasn't much story progression until you beat a boss that was another witch
-i played it on a website called gamesxl so it was most likely a flash game
-i played it 5 or so years ago but it may have been released earlier

I never beat the game and I randomly thought of it and couldn't remember the name, so it would be a great help if someone recognizes it!
