In terms of basic game play this is a pretty solid retro feeling platformer
The world felt too big and sparse to me. I spent a lot of time walking without anything interesting happening and then I'd be at a dead end and have to walk back. I think I would have enjoyed this more if about 60% of the empty area and places where it's just fairies drifting around were removed.
I reached an area in the lower left that is maybe supposed to be dark? It was unclear. I stepped through what seemed like it might be a gap in the wall leading to a new section but then fell instead and found a key in a lit area below. By jumping randomly in the dark I managed to get back up to the level above but I could never get out to the initial area or get further to the left past the candlesticks. And then a duck sat on my head? That may have killed me but the darkness was hiding my life meter so I couldn't really tell.
