Our goal was to make simple and straightfoward games that could be played by anyone. I agree with you that 10 pumpkins is a bit too much!
About the flipping back on will, it would add too much constraints to gameplay, and could be a lot more confusing to more casual players, but I see your point!
Unfortunately dragging parts to face was a bit harder to develop and would take too much time!
Thanks for the feedback and thanks for playing! :)
