The Map of Masks
Here's the paper prototype. I've played it with 4 kids and 4 adults. Age has a big impact on what is seen as fun. For instance, my youngest daughter does not agree with the idea of having your mask stolen by the other player. While most adults see this is a one of the more fun aspects.
This prototype is quite simple; you roll the dice to walk around, and try to pcik up and stack as much masks as possible. The 'cat' will allow you passage through cat-walls. But there is nothing regarding combo's yet.
The stacking of masks works well. There is a minimum size of a mask for it to look decent, this then influences the size of the map. So everything is connected.
