A well made puzzle-platformer with a quirky movement mechanic.
Definitely spent more than 6 minutes playing the game xD
The multitude of checkpoints is really nice, would maybe add some visual indicator for them
You have a nice visual and audio indicator of the cauldron being charged, but only a visual indicator when it loses charge, would recommend either and active audio sfx and/or a "discharge" sfx.
The game's tutorials are very well done. To make the input 100% clear in game, i'd recommend adding the gif on you game page into the game. Though the existing guidance is sufficient.
Very well done :D
