Fun game, my highscore is 28.
I really like the control scheme, I found it rather intuitive and when I failed its because I messed up. I am also really happy that you made changes to the fans based on whether or not the associated key was pressed. I feel like you could take the readability further by having the fans not be blowing unless the player is holding the key down. However, as it stands it is fine without. Honestly, just a nice simple game.
Nice work.
