You even manage to avoid text at the title screen, great job! :D

The control feels good. The dash/vanished and fly instead of jumping is a fun twist of usual platformer (or should I call this game genre "Metroidvania"?). Sometimes, when I fly and then press left/right, the ghost kind of losing power and falling down, but it feels minor.

Anyway, great job. :D :D :D It's short but I feel good playing a game until finish.
