In this 2D puzzle platformer the player explores some ruins and finds a mysterious being in a tank. As you take the tank the floor collapses. You wake up deep in those ruins and find some mechanisms. To find your way out, you must solve puzzles but activating switches consumes the liquid in the tank you carry. Meaning you must find the most optimized way to solve those puzzles so the mysterious being doesn’t run out of its vital liquid. If the mysterious being dies, the game is over. 

Note: some mechanisms can be filled/emptied multiple times

A game made during Ludum Dare 46 “Keep it alive”. Every asset was made by the Donut Dodo Team. Even sound effects were made by mouth!

(As of today there isn’t any music in menus and cutscenes.)

Incredible game! I got involved in their universe, by the way, do you already have a cohesive universe or is it just limited in this demo?

Hi! Thanks for the kind words :D This game was a tiny project made for the Ludum Dare 46 game jam, we set up some storytelling guidelines but we have no plan to expand on this universe as for now.
