A downloadable Hydrodynamic puzzler for Windows

Download NowName your own price

Flow Problem is a simple but challenging retro puzzle game where you have to try and guide as much water as possible down to the bottom of the screen. Hindering you are obstacles such as rocks, fire rocks and blocks of ice, which each affect the water in different ways, You also have the effects of sand to deal with.

The game itself is completely playable but there is no sound. There are 20 increasingly difficult levels to beat (or beat your own high score on), as well as a random level generator.

Puzzle game fans should get some fun out of this. :-)


For a more polished game on a similar theme, see Snow Problem, available both here on Itch and on Steam.

Cool water physics!  I wish the water would travel a bit faster though.

So do I! Because everything is worked out per pixel and the get / set pixel commands are quite slow, I haven't found a way to optimise it better. May ask someone smarter than me to try :-)
