That was a really satisfying play. After completing the puzzles, I built myself a whirlpool in the sandbox (a.k.a. enclosed a fluid source with cubes) which ended up actually working. Did you implement the fluid dynamics from scratch during the jam?
Yay! Satisfying was the goal! Nice job on the whirlpool, I'll have to give that a try
The fluid dynamics and shaders come from NVIDIA Flex. I already had the custom build of UE4.18 installed so the work during the jam was learning to use and customize it in Unreal's particle system.
