A puzzle game about unblocking stuff.
- Maybe things will automatically move some way (like rocks falling down, or animals wanting to move to their home/nest),
- Maybe water will automatically flow one way or another
In any case, at the start the puzzle these movements are blocked in many ways, and you need to take all the right turns to unblock things in the right order to make them move/go/flow to where they should be.
I just really like the name Bottlenecky. The actual idea never had enough concrete details for me to pursue it.
