Outpour

Here is an excerpt from Outpour's Steam description:

Outpour is a puzzle game where gargoyles manipulate the flow of interactive bodies of water to solve levels. In order to win, push and pull blocks to change how water flows throughout the stage. Sever all possible drainage points until only one remains, and traverse your way to the remaining runoff to make your gargoyle become a spout.

Water permeates throughout the stage via a procedural grid-based system. It's intuitive, yet full of unexpected complexity and delights.

This game invites the player to explore its systems through various thoughtfully designed mechanics such as water-blocking blocks, floating rafts, traversable tightropes, and many watery intricacies, providing over 100 detailed hand-crafted levels.
