So I wanted to start with a really simple concept, initially there would be a pipe that each HOLE would have to travel. The final destination would be marked with a yellow location symbol.
Basically you grab the hole and avoid coming into contact with anything. It was fun in the beginning, but soon after it became boring.
Then I realized, hey, why not put some traps along it?
TBC.
Maybe a monster running on the pipes too? Like super mario
