That's such a refreshing idea! Loved it.
If you could, maybe, increase the timer or keep the controls displayed, it would be great
Oh, even better! How about, each time player gets one part right (like left eyebrow matches the mask, for eg.), the timer gain 1 or 2 seconds? That way player will be motivated to strategize, which part of face to work on first.
If you are planning on motivating the player to handle all the controls at once, then maybe just increase the time.
These are just suggestions, but even without them, your game stands out as a unique piece of game :)
@Benjamin Pillbrow, please do check my replay to your comment in my game. It would help a solo dev/designer like me a lot :)
