Hi, nice game ! I really like the art / music
As you mentioned in the description, the gameplay is very simple, perhaps too luck-based. I find it a bit sad that there's so much randomness involved in this game. You are basically only allowed to continue the level if nobody is watching, which isn't a lot of fun, especially if it takes a lot of time. Perhaps allowing the art-bar to not reset when paused could remove some of the luck-based elements while keeping the original idea.
Anyway, cheers on your entry !
