I have 2 issues. But it could be just me.
1. The game screen is small like 1/4 of full screen.
2. I keep pressing the corresponding keys when fairies enter the zone but nothing seems to react.
3. The fonts of each key look so fancy it's hard to read it.
4. There are too many keys to press! :')
Unfortunately at this state the game is unplayable for me. Cool arts tho.
