Thanks ! For the scrolling issues, the current solutions are either to play with fullscreen option on itch.io (I just added the button as suggested by Itooh), or to play the game on a dedicated html page that doesn't scroll (I'll add a link in description)
Thanks for sharing your time :) I think my best is around 17 seconds, but it's mostly luck to get a "good" time (not even sure what's the best possible time, honestly), as the ghosts' movements are totally random.
I just added the timer because I didn't have time to add any other sort of score or challenge in the game ^^
