First of all, I have to say, I absolutely love the art style and I heally think some SFX would elevate the overall mood to the next level. I really like how the light works and highlights both your surroundings and the coins.
I really enjoyed how predictable the ennemies are, meaning you can really plan your moves towards the coins or the bottom.
I particularly like how rare the coins are, which makes you want to keep thee for the end when the game becomes more difficult.
I think the random effect you get when getting a coin is a neat idea, and how you did it was very cool however it may not be perfectly clear what each effect does.
I would have preferred maybe a slightly smaller hit box for the fae (it felt a bit frustrating sometimes) and you know having the ability to fly somehow for a winged fae would feel nice (even though I understand this may break your game).
Overall, very well done I enjoyed it quite a lot!
